Apple expands advanced VCSEL manufacturing with II-VI

Apple has committed a further $410 million to II-VI to create additional capacity for manufacturing VCSEL devices and accelerate delivery of future components for iPhone.

II-VI manufactures vertical-cavity surface-emitting lasers (VCSELs) that help power Face ID, Memoji, Animoji, and Portrait mode selfies. Apple also works with II-VI to manufacture lasers used in the LiDAR Scanner — technology that helps deliver faster, more realistic augmented reality experiences and improves autofocus in low-light scenes in photos and videos.

The new award, which builds on an initial $390 million awarded from Apple’s Advanced Manufacturing Fund in 2017, is expected to resul in 700 jobs in Sherman, Texas; Warren, New Jersey; Easton, Pennsylvania; and Champaign, Illinois.

“We established Apple’s Advanced Manufacturing Fund to support American businesses creating next-generation technology and the jobs of tomorrow,” said Jeff Williams, Apple’s chief operating officer. “II-VI shares our commitment to push the boundaries of innovation and we’re proud to be extending our work together across the country.”

“The partnership between Apple and II-VI sets the stage for a new wave of breakthrough technologies that we believe will enable a wide range of applications that will benefit our world for decades to come,” said Dr. Vincent Mattera Jr., II-VI’s CEO. “We are incredibly grateful for Apple’s support which has allowed us to expand our manufacturing capacity and scale our operations across the US.”

Lumentum introduces multi-junction VCSEL arrays for sensing applications

Lumentum introduced new high-power and high-efficiency five and six junction vertical cavity surface-emitting laser (VCSEL) arrays for advanced consumer, automotive LiDAR, and other 3D sensing applications.

Lumentum's multi-junction VCSEL arrays emit at 940 nm and 905 nm and are manufactured on the same production lines as current high-volume VCSEL array products serving the consumer electronics market. The company said these new VCSEL arrays enable much lower power dissipation, very high slope efficiencies, and record-breaking optical peak powers compared with existing devices. Optical powers exceeding 2 W per individual VCSEL emitter have resulted in over 800 W of peak power from a compact one square millimeter sized VCSEL array. The peak optical power, low thermal dissipation, and small die size of these new multi-junction VCSELs arrays are important to extending their use to high performance all-solid-state medium and long-range LiDAR.

"Automotive, consumer, and industrial customers increasingly need higher performance VCSEL arrays to drive increased functionality and adoption of LiDAR and 3D sensing enabled products," said Dr. André Wong, Vice President of 3D Sensing Product Line Management. "Our latest multi-junction VCSEL arrays continue our long history of pioneering innovative optical solutions in close collaboration with customers. These new products leverage the well proven high-volume, 6-inch wafer supply that we established more than four years ago."

In addition to these new high-power VCSEL array illuminators, Lumentum also offers a wide variety of optical solutions for 3D sensing, automotive, and LiDAR applications. These include VCSEL solutions for vehicle in-cabin monitoring, high-performance Gallium Arsenide and Indium Phosphide edge-emitting laser chips for 3D sensing and LiDAR, and 1550 nm narrow-linewidth DBR diode lasers for long-range frequency-modulated continuous-wave (FMCW) coherent LiDAR.

II‐VI develops VCSEL module for driver monitoring systems

II‐VI introduced its vertical cavity surface emitting laser (VCSEL) flood illuminator modules for driver and occupancy monitoring systems in vehicles.

II-VI said its new VCSEL flood illuminator modules emit higher optical power and with a narrower spectral width than infrared LEDs currently used in existing driver monitoring systems, enabling substantial improvements in system performance. The infrared light emitted from II-VI’s flood illuminator modules can be modulated to frequencies greater than 100 MHz, making them ideal for 3D time-of-flight cameras for driver and occupancy monitoring systems. The modules are expected to be AEC-Q102 certified for automotive applications in the second quarter of calendar 2021.

“Our new VCSEL flood illumination modules integrate VCSEL chips, photodiodes, and diffuser optics, achieving a greater level of vertical integration and value for our customers,” said Dr. Julie Eng, Sr. Vice President, Optoelectronic & RF Devices Business Unit. “We leveraged our in-house 6-inch GaAs technology platform to successfully scale production of our VCSEL arrays for consumer electronics, and we look forward to ramping production of flood illumination modules for in-cabin sensing in automotive as the demand grows.”

II-VI intros double-junction VCSEL arrays for 3D sensing

II‐VI introduced its double-junction vertical cavity surface-emitting laser (VCSEL) arrays for next-generation world-facing 3D sensing applications.

II-VI’s new VCSEL arrays are based on a double-junction technology that doubles the power output per VCSEL emitter and improves the power conversion efficiency to 56%, compared with 46% in existing single-junction technology. The company says this can be leveraged for a number of differentiating benefits, including higher output power to sense farther and wider, reduced battery power consumption, and smaller size to achieve lower cost and to enable more inconspicuous designs.

II-VI’s double-junction VCSEL arrays emit at 940 nm, and their steep slope efficiencies enable very short pulses of very high peak powers. The VCSEL arrays are designed for low-cost non-hermetic packaging and, like the single-junction arrays, can be reliably and cost-effectively scaled in total power by increasing the number of emitters per chip. They can also be produced in high volume on II-VI’s vertically integrated 6-inch platform.

“We have developed over the years strong partnerships with our customers, closely collaborating on the development of long-term technology and product roadmaps aimed at providing breakthrough solutions and continuously elevating user experience in 3D sensing,” said Dr. Julie Eng, Sr. Vice President, Optoelectronic & RF Devices Business Unit. “A few years ago, we successfully scaled our vertically integrated GaAs optoelectronics technology platform from 3-inch to 6-inch, which enabled us to shorten our development cycles and introduce new products to meet aggressive market windows. We are now once again evolving the platform, this time with a leap to double-junction technology that we believe will unlock exciting new use cases, such as farther depth of sensing in world-facing applications and seamless integration into consumer products for AR and VR applications.”

Philips sells Laser Diode Division to TRUMPF

Philips will sell 100% of its Photonics GmbH division to TRUMPF. Financial terms were not disclosed.

Philips Photonics, which iss headquartered in Ulm, Germany, designs, manufactures, markets and sells VCSEL-based solutions for data communications, consumer and industrial applications. Its product portfolio ranging from high speed VCSELs (vertical-cavity surface-emitting lasers) for data communication to infrared illumination modules for security, surveillance and night vision applications, from single mode VCSELs for sensing applications to intelligent Laser Doppler sensors for accurately measuring velocity and distance. Philips Photonics' laser diodes are manufactured in a high-tech facility in Ulm. Further locations are Aachen, Eindhoven in the Netherlands, and sales offices in Shenzen, Shanghai, and Qingdao in China. Photonics GmbH employs around 280 people.

TRUMPF said the acquisition opens up a new market segment. TRUMPF's existing business includes high-power diode lasers.

"With this acquisition, we want to open up new product fields and expand our existing portfolio at a strategically important point," said TRUMPF boss Nicola Leibinger-Kammüller.

"Since our foundation in 2000, we have grown strongly. More than half a billion cell phones worldwide are equipped with laser diode technology from Philips Photonics," said Joseph Pankert, Business Leader of Philips Photonics. "We are very excited to become part of TRUMPF. This will ensure that the division can continue to grow in a highly innovative company in the future," Pankert continued.
