Stanford researchers train neural network using optical chip

Researchers at Stanford University have demonstrated the ability to train artificial neural networks directly on an optical chip.

Neural network processing currently relies on conventional computers.  The Optical Society's journal for high impact research, Stanford University researchers report a method for training these networks directly in the device by implementing an optical analogue of the ‘backpropagation’ algorithm, which is the standard way to train conventional neural networks.

“Using an optical chip to perform neural network computations more efficiently than is possible with digital computers could allow more complex problems to be solved,” said research team leader Shanhui Fan of Stanford University. “This would enhance the capability of artificial neural networks to perform tasks required for self-driving cars or to formulate an appropriate response to a spoken question, for example. It could also improve our lives in ways we can’t imagine now.”

MIT: a new technique for assembling on-chip optics and electronics separately

A team of researchers led by groups at MIT, the University of California at Berkeley, and Boston University, have developed a technique for assembling on-chip optics and electronics separately using existing manufacturing processes.

The work, which is described in an article in the latest issue of Nature, allows the addition of optical communication components onto chips with modern transistors.

“The most promising thing about this work is that you can optimize your photonics independently from your electronics,” says Amir Atabaki, a research scientist at MIT’s Research Laboratory of Electronics and one of three first authors on the new paper. “We have different silicon electronic technologies, and if we can just add photonics to them, it’d be a great capability for future communications and computing chips. For example, now we could imagine a microprocessor manufacturer or a GPU manufacturer like Intel or Nvidia saying, ‘This is very nice. We can now have photonic input and output for our microprocessor or GPU.’ And they don’t have to change much in their process to get the performance boost of on-chip optics.”

University of Guam lights 100G GOREX

The University of Guam is now connected to the global Research and Education Network fabric at 100G.

The GOREX network—or Guam Open Research & Education eXchange—connects Guam to Hawaii and California via the new SEA-U.S. fibre-optic submarine cable.

The Marine Laboratory and the Water Environmental Research Institute at the university are two of the academic groups expected to benefit the most from GOREX at the onset, although UOG president Robert Underwood believes the true impact to the island community is in the opportunity for data access, exchange, and analysis in other fields such as healthcare, economics, and the social sciences.

“We can now conduct research at complex levels, not just for the sciences, but in other fields as well,” said Underwood. “Think about the issues that we discuss as a society and how we make many decisions with limited data. GOREX gives our students and faculty the tools to truly exchange and analyze large amounts of data in any number of fields with other institutions all over the world. And as a university, it is our responsibility to report our findings back to the community. That’s the impact.”

The Pacific Wave Peering Exchange continues to expand

Pacific Wave International Exchange and its peering and science DMZ fabrics will be extended to Texas’s Lonestar Education and Research Network (LEARN) and Oklahoma’s OneNet thanks to support from the National Science Foundation.

The Pacific Wave SDX, which is a project of the Corporation for Education Networking in California (CENIC) and Pacific Northwest Gigapop (PNWGP), is an integral component of the international effort to interconnect research and education networks using Software Defined Networking (SDN).  Pacific Wave operates multiple open exchange peering points available at three U.S. Pacific coast locations, including the Bay Area (Sunnyvale and Palo Alto), Los Angeles (three sites), and Seattle; three U.S. interior locations in Denver, Albuquerque, and El Paso; and two sites in Tokyo, Japan. It comprises multiple, geographically diverse 100Gbps connections – in Seattle, Los Angeles and Chicago – to Internet2’s backbone nodes and full range of advanced network capabilities. Pacific Wave also operates an SDX testbed with access points in Los Angeles, Seattle and Sunnyvale, and including teaming relationships with StarLight, WIDE/T-REX and others to pilot more global interoperability of next-generation SDX capabilities.

LEARN and OneNet will connect to Pacific Wave via the Western Regional Network (WRN). WRN is an R&E extension of Pacific Wave, created and supported by a collaboration of the major Western Regional R&E optical networks: Front Range Gigapop (CO and WY), New Mexico Gigapop, University of Hawaii, Pacific Northwest Gigapop (WA, AK, MT, ND) and CENIC (CA). WRN employs a dedicated 100Gbps wavelength-based network infrastructure, including “dark channels” provided by Internet2, that spans the West and also reaches Pacific Wave’s international exchange point collaborator, StarLight, in Chicago, thereby making most European R&E networks directly accessible to WRN participants.

AT&T Foundry and Caltech plan Alliance for Quantum Technologies

The AT&T Foundry innovation centre in Palo Alto, California announced that it is teaming with the California Institute of Technology to form the Alliance for Quantum Technologies (AQT), with the aims of bringing together industry, government and academia to accelerate the development of quantum technology and to address practical applications.

The collaboration will also establish a research and development program named INQNET (INtelligent Quantum NEtworks and Technologies), which will focus on meeting demand for capacity and security in communications leveraging advanced quantum networking technologies.

Under the new initiative, AT&T and Caltech, through AQT and INQNET, are seeking to create the model for technology development between academic institutions, industry and national laboratories. One of the first demonstrations of intelligent and quantum network technologies will involve quantum entanglement distribution and benchmarking and validation studies utilising commercial fibre provided by AT&T.

AT&T noted that quantum networking is expected to enable a new era of super-fast, secure networking, and through the AT&T Foundry it will support testing of relevant technologies for commercial applications.

AT&T explained that quantum computers will be unlike current systems, being effectively complex physics experiments employing cryogenics for cooling, lasers and other solid-state, electronic, optical and atomic devices. As a result, transitioning quantum computing from the R&D lab into the real world for practical applications will mean solving numerous technical and engineering challenges.

The science behind quantum computing is complex, extending across disciplines such as physics, engineering, computer science and applied mathematics, with the fundamental concept involving the application of the laws of quantum mechanics to processing and distributing information.


Such quantum computing systems are expected to provide exponentially greater computing power, while quantum networking entails linking quantum computers and devices together to create faster and more secure networks with capabilities beyond what is possible using conventional processors.

University of Cambridge: Liquid Light Switch

Researchers at the University of Cambridge announced a miniature electro-optical switch with the potential for more energy-efficient signal processing.

The switch can change the spin – or angular momentum – of a liquid form of light by applying electric fields to a semiconductor device a millionth of a metre in size.

The project, which was conducted at the Cambridge NanoPhotonics Centre with funding from the UK Engineering and Physical Sciences Research Council (EPSRC), the European Research Council (ERC) and the Leverhulme Trust, leverages a state of matter called Polariton Bose-Einstein condensate, which enables the switch to mix electric and optical signals.

Researchers Announce First All-Photonic Nonvolatile Memory Chip

Researchers from Oxford University, the University of Münster, the Karlsruhe Institute of Technology and the University of Exeter have created the world’s first all-photonic nonvolatile memory chip.

A paper published this week in the journal Nature Photonics describes how intense pulses of light sent through a waveguide can change the state of Ge2Sb2Te5 (GST) material — the same as that used in rewritable CDs and DVDs. The pulse of light causes the material to melt and assume an amorphous structure.

Less intensive pulses of light cause the material to enter into a crystalline state. The difference in state affects how much light is transmitted in subsequent pulses, enabling data to be stored as optical bits as either 1s or 0s.  The state can be preserved for extended periods of time. Moreover, the researchers say the optical bits can be re-written at frequencies of up to one gigahertz.

FIU/AmLight Deploys ONOS and SDN-IP Across the Americas

Florida International University (FIU) has deployed the Open source SDN Network Operating System (ONOS) on Americas Lightpaths (AmLight), creating a software-defined networking (SDN) facility entirely based on OpenFlow. Five Latin American research and education networks (RENs) – Academic Network at Sao Paulo (ANSP), Brazilian National Research and Education Network (RNP), Latin American Advanced Networks Cooperation (RedClara), National University Network of Chile (REUNA) and the Caribbean Knowledge and Learning Network (CKLN) – interconnect Brazil, Chile and the Caribbean with the U.S. via a virtual slice of the AmLight network.


This implementation takes advantage of AmLight's ability to create virtual network slices using Internet2's FlowSpace Firewall. Symmetrically to a previously announced OpenFlow-based Internet2 ONOS deployment, the AmLight network can communicate with the Internet2 ONOS slice through a shared (legacy) BGP router deployed at FIU in Miami. Through Internet2, AmLight is linked to other ONOS network facilities such as GEANT in Europe.

The solution deployed is able to: provision L3 connectivity without using legacy routers in the network core; transform ASs running OpenFlow into IP (BGP) transit networks; allow an SDN network to seamlessly connect to the rest of the Internet using BGP thus providing a powerful migration strategy; and aggregate different SDN administrative domains into BGP confederations, making the control plane more scalable.

"The deployment of ONOS represents groundbreaking work in the field of SDN and networking," said Dr. Julio Ibarra, Assistant Vice President for Technology Augmented Research at FIU. "We're not just connecting one organization to another, but are connecting a dynamic global software-defined REN to create an open instrument for collaboration. This accelerates research discovery, advances education, and improves the delivery of public services while offering the benefits of ONOS' next-generation networking technology for improved learning, collaboration and innovation."

"The production deployment provides invaluable real-world insight from end users and network engineers, and the testbed aspect of the deployment enables experimentation to further improve and harden ONOS," said Guru Parulkar, Executive Director and Board Member at ON.Lab. "The ONOS project values collaboration with R&E network operators and their users, and the ONOS platform enables R&E network operators to rapidly innovate and better serve their communities."
