Silicon photonics pioneer Michal Lipson elected by The Optical Society

 Dr. Michal Lipson, Eugene Higgins Professor at Columbia University, has been elected members of The Optical Society (OSA) to serve as the society’s 2021 Vice President. Lipson’s four-year commitment to OSA’s Board of Directors consists of serving one year as vice president in 2021, followed by one year as president-elect in 2022, president in 2023 and past president in 2024.

“In the field of silicon photonics, Lipson is a pioneer whose work in tailoring the electro-optic properties of silicon and advancing research and development is world-renowned,” said OSA CEO Elizabeth Rogan. “Her contributions to OSA and the optics and photonics community have been extraordinary and the society will continue to benefit from her serving in this key leadership role.”

Dr. Lipson pioneered critical building blocks in the field of silicon photonics, which today is recognized as one of the most promising directions for solving the major bottlenecks in microelectronics. In 2004, she showed the ability to tailor the electro-optic properties of silicon (Almeida, et al., Nature 2004 with more than 1300 citations and Xu et al Nature 2005 with more than 2000 citations) which represented critical advances that led to the explosion of silicon photonics research and development. The number of publications related to silicon photonic devices and systems is now more than 50,000 a year. Many of these publications are based on Lipson’s original papers published since 2001. 

OSA members also elected two directors-at-large to serve on the OSA Board of Directors for the 2021-2023 term:

  • Dr. Joyce Poon is a Director of the Max Planck Institute of Microstructure Physics, Professor of Electrical and Computer Engineering at University of Toronto, Canada and an Honorary Professor in the Faculty of Electrical Engineering and Computer Science at the Technical University of Berlin, Germany. She and her team specialize in integrated photonics on silicon. She currently serves as an Associate Editor for Optics Express. Poon founded the OSA Student Chapter at the California Institute of Technology, USA where she earned her Ph.D. She subsequently built a research program centered on silicon integrated photonics for telecom applications at the University of Toronto, Canada. 
  • Dr. Ulrike Woggon is Professor of Experimental Physics, in particular Nonlinear Optics, at the Institute for Optics and Atomic Physics of the Technical University Berlin (TUB).  In 1985, she received her Ph.D. from Humboldt University in the field of nonlinear optics in semiconductors. Her research interests, documented by more than 200 refereed publications and approximately 7,500 citations, several book chapters and numerous invited lectures as well as third-party funding, are in the field of nanophotonics, ultrafast spectroscopy, solid-state optics and photonic materials. Woggon is one of the founding members of the Berlin School of Optical Sciences and Quantum Technology (BOS.QT). She became an OSA Fellow in 2010, and has served as chair or member on several OSA program committees. 

Lipson and the new directors-at-large will begin their terms on 1 January 2021.

The Optical Society opposes U.S. government restrictions on student visas

The Optical Society (OSA) stands opposed to new restrictions by U.S. Immigration and Customs Enforcement (ICE) on the Student and Exchange Visitor Program. Here is the statement of Elizabeth Rogan, CEO, The Optical Society (OSA):

"The Optical Society (OSA) strongly opposes the decision by U.S. Immigration and Customs Enforcement (ICE) to modify temporary exemptions for current and future nonimmigrant F-1 and M-1 visa students attending schools in the U.S. Under these new rules, nonimmigrant F-1 and M-1 students in the Student and Exchange Visitor Program are prohibited from taking a full online course load while remaining in the U.S. In addition, they will not be allowed to enter the country from abroad. Students who cannot transfer to a school with in-person instruction on such short notice will likely face deportation."


"The decision has serious implications for students as academic institutions across the U.S. and globally transition to online offerings to mitigate the risk of covid-19. Students in STEM and other fields attending U.S. schools will be unable to start or complete their academic work. Their lives will be uprooted, and degrees will be abandoned. The new rules are the latest in a series of increasingly exclusionary and shortsighted immigration proclamations by the Administration.

"OSA supports the civil liberties and human rights of all scientists and engineers and declares its support for the 1948 United Nations Universal Declaration of Human Rights. Scientific progress needs governments to respect basic human rights in order to achieve its full potential. Governments must avoid interference with the human rights of scientists and engineers as they carry out their professional work. The ICE decision restricts the training, education, and work of students and runs counter to OSA’s core value of inclusivity."

"As we search for scientific solutions to global challenges such as the pandemic, there could hardly be a worse time to shut the country off from talented students. We urge U.S. government officials to reverse this destructive decision. Students must be allowed to continue their studies should their institutions maintain online-only courses during the pandemic."

Researchers test quantum entanglement from nanosatellite

Researchers from the National University of Singapore and NASA generated and detected quantum entanglement onboard a CubeSat nanosatellite orbiting the Earth.

The experiment demonstrated that a miniaturized source of quantum entanglement can operate successfully in space aboard a low-resource, cost-effective CubeSat that is smaller than a shoebox (10 cm × 10 cm × 10 cm).

The photon-pair source consisted of a blue laser diode that shines on nonlinear crystals to create pairs of photons. Achieving high-quality entanglement required a complete redesign of the mounts that align the nonlinear crystals with high precision and stability. The nanosatellite, named SpooQy-1, was deployed into orbit from the International Space Station on 17-June-2019. The instrument successfully generated entangled photon-pairs over temperatures from 16 °C to 21.5 °C.

“In the future, our system could be part of a global quantum network transmitting quantum signals to receivers on Earth or on other spacecraft,” said lead author Aitor Villar from the Centre for Quantum Technologies at the National University of Singapore. “These signals could be used to implement any type of quantum communications application, from quantum key distribution for extremely secure data transmission to quantum teleportation, where information is transferred by replicating the state of a quantum system from a distance.”

A report on the project was published in Optica, The Optical Society's (OSA) journal for high impact research.

The researchers are now working with RALSpace in the UK to design and build a quantum nanosatellite similar to SpooQy-1 with the capabilities needed to beam entangled photons from space to a ground receiver. This is slated for demonstration aboard a 2022 mission.

Global Environmental Monitoring and Measurement in Scotland

The network of 25 sensors will be installed in primary and secondary schools across Glasgow, Scotland to collect real-time information on emissions of CO2 and various noxious gases in the city’s air. The trial is part of the Global Environmental Monitoring and Measurement (GEMM) initiative, a collaboration between the University of Strathclyde; Stanford, the University of California at Berkeley, The Optical Society (OSA), the American Geophysical Union (AGU), the Met Office, and the National Physical Laboratory, UK.

“This project will deliver the type of data necessary to drive efforts in Glasgow and other cities to reduce emissions and greenhouse gases,” said Elizabeth Rogan, CEO, The Optical Society (OSA). “The GEMM initiative is developing measurement technologies to improve climate change models and inform decision-making in both the public and private sector.”

Professor Allister Ferguson, University of Strathclyde and co-lead of the project said, “As the climate changes rapidly, public and private decision-makers around the world are facing an ever-increasing need for more accurate environmental data, improved measurements, and forecasting models to predict the future course of the environment and, where possible, develop strategies to adapt to or mitigate these environmental and climate-change caused disruptions.

Co-lead Dr. Thomas Baer, Director of Stanford Photonics Research Center at Stanford University, USA and a Visiting Professor at Strathclyde said, “While efforts to reduce GHG emissions have made great strides, particularly when it comes to electricity generation, heating and transport remain two challenging areas. Being able to monitor in real-time the GHG emissions caused predominately by traffic, policymakers will be able to make informed decisions and see near-immediate results.”

OIDA Quantum Photonics Roadmap: Every Photon Counts

A newly released Quantum Photonics Roadmap: Every Photon Counts, which was produced by OSA Industry Development Associates (OIDA) in collaboration with Corning, clarifies the applications and timing for quantum technologies and specifies improvements in optics and photonics components needed to enable commercialization. It covers the three major application areas: quantum sensing and metrology, quantum communications and quantum computing.

Commercialization of products such as quantum sensors for GPS-free navigation and field-deployable quantum repeaters for communications will be significant milestones in an emerging market but more investments in product engineering are critical. Lower SWAP-C devices would enable progress, for example, across multiple sensing categories, and integration of these systems onto photonic chips is a critical path to doing so. While some integration is possible today, more on-chip functionality (e.g., sources, modulators, switches) is needed.

“While the field still needs breakthroughs in quantum science, such as a quantum repeater, the photonics technology already largely exists for laboratory experiments,” says Tom Hausken, senior industry advisor, The Optical Society (OSA). “The product engineering -- low size, weight, power and cost -- is missing, or it is applied to a specific customer application, without benefit to the rest of the field. The need is analogous to the talent shortage, not just with scientists, but with engineers in photonics, microwave and control electronics, packaging and cryogenics who have the specialized expertise to bring the technology to market.”



Although the quantum technology market is still in the early stages, the optics and photonics community already supplies critical enabling components to research and development labs in the near term to ensure progress. OIDA estimates sales of optics and photonics for lab equipment used by quantum researchers at about US$100 million per year. The commercial market for quantum end-use products is expected to rise to billions of dollars by 2030.

“The real impact of quantum technology is what it can do, which could be far greater than the market for the technology itself,” Hausken adds. “The fear of missing out (FOMO) on that impact on competitiveness and security is driving funding in quantum research, which OIDA estimates at about US$2 billion annually.”

The public and private sectors worldwide are making multi-year investments in quantum technologies with an end-goal of market ready applications. In the U.S., the National Quantum Initiative Act, a multi-agency plan, proposes US$1.2 billion in funding for quantum information science over five-years. The European Union’s Quantum Flagship program is budgeted at 1 billion euros over a ten-year period.

Investments in the product engineering of quantum technology could support classical applications as well. For example, investments in lower loss integrated photonics and single-photon detectors could yield benefits in classical optical communications and low-light imaging, respectively. Integrated photonics offers many promising solutions for quantum technology, at a time when it offers multiple solutions in other fields.

  • Light-based sensing technologies allow for more accurate monitoring of environmental health as countries assess climate change;
  • Developments in imaging and remote sensing are enabling sustainable agriculture goals that help mitigate food shortages.

“These visionary leaders have shared thoughtful articles that we hope will resonate with scientists and non-scientists alike. Each topic also connects to current and future solutions around the pandemic we are living through now. IEEE Photonics Society is proud to support this initiative.” - IEEE Photonics Society President Carmen Menoni, Colorado State University, USA.

"SPIE is proud to be one of the founding sponsors working to establish the International Day of Light. The solutions to today's global challenges will all involve light-based technologies, either directly or indirectly. Highlighting this impact is crucial, as we must broaden the awareness of light in our lives across the globe," said SPIE President John E. Greivenkamp, University of Arizona, USA

 “OSA’s partnership with our fellow societies to support this campaign is essential to building public awareness of the importance of the science of light and light-based technologies. Light has to be on the forefront of minds for voters, policy-makers, STEM educators and - most importantly - the next generation of our workforce,” commented OSA President Stephen D.

Researching chip-based devices for quantum-secured communication

Secure quantum key exchange can be accomplished between two chip-based devices, according to a paper published in Optica, The Optical Society's (OSA) journal for high-impact research. Two devices measuring just 6 x 2 millimeters potentially can operate of a fiber link of up to 200km. The chip-based devices contain all the optical components necessary for quantum key distribution.

The new quantum key distribution devices contain highly complex circuits that control the weak photonic signals of light necessary for quantum key distribution. Nanoscale components in the chips make it possible to drastically reduce the size and power consumption of quantum communication systems while maintaining high-speed performance vital for modern networks.

A demonstration has been performed at the University of Bristol Quantum Engineering Technology Labs.

“Chip-based devices significantly reduce the barrier for widespread uptake of quantum-secured communication by providing a robust, mass-manufacturable platform,” said research team leader Henry Semenenko from the University of Bristol, UK. “In the future, these devices will form part of a standard household connection to the internet that keeps our data secure regardless of advances in computing technology.”

“With its densely packed optical components, our chip-based platform offers a level of precise control and complexity not achievable with alternatives,” said Semenenko. “It will allow users to access a secure network with a cost-effective device the same size as the routers we use today to access the internet.”

Silicon-based optical parametric oscillator transforms wavelengths

Researchers from the National Institute of Standards and Technology (NIST), University of Maryland, and University of Colorado are developing a new optical parametric oscillator (OPO) light source that can produce output light at different wavelength than the input light. In addition to creating light at visible wavelengths, the OPO simultaneously generates near-infrared wavelengths that can be used for telecom applications.

The research is published in Optica, The Optical Society's (OSA) journal.

“Our power-efficient and flexible approach generates coherent laser light across a range of wavelengths wider than what is accessible from direct chip-integrated lasers,” said research team leader Kartik Srinivasan. “The on-chip creation of visible light can be used as part of highly functional compact devices such as chip-based atomic clocks or devices for portable biochemical analyses. Developing the OPO in a silicon photonics platform creates the potential for scalable manufacturing of these devices in commercial fabrication foundries, which could make this approach very cost-effective.”

“Nonlinear optical technologies are already used as integral components of lasers in the world’s best atomic clocks and many laboratory spectroscopy systems,” said Xiyuan Lu, first author of the paper and a NIST-University of Maryland postdoctoral scholar. “Being able to access different types of nonlinear optical functionality, including OPOs, within integrated photonics is important for transitioning technologies currently based in laboratories into platforms that are portable and can be deployed in the field.”

The Optical Society said the silicon-based device may enable variety of photonic applications across a range of wavelengths.

Some highlights:
The OPO based on a microring made from silicon nitride.
It is fed by approximately 1 milliwatt of infrared laser power — about the same amount of power found in a laser pointer.
As the light travels around the microring it increases in optical intensity until powerful enough to create a non-linear optical response in silicon nitride.
This enables frequency conversion, a nonlinear process that can be used to produce an output wavelength, or frequency, that is different from that of the light going into the system.
The device was used to convert 900-nanometer input light to 700-nanometer-wavelength (visible) and 1300-nanometer-wavelength (telecommunications) bands.
The OPO accomplished this using less than 2 percent of the pump laser power required by previously reported microresonator OPOs developed for generating widely separated output colors.
