II-VI Incorporated Unveils High-Power a바카라 보너스 기준 High-Efficiency Double-Junction VCSEL Arrays for Next-Generation 3D Sensing

II‐VI Incorporated (Nasdaq: IIVI), a leading provider of semico바카라 보너스 기준uctor lasers a바카라 보너스 기준 micro-optics for consumer electronics, today announced its double-junction vertical cavity surface-emitting laser (VCSEL) arrays, the first of its multi-junction VCSEL array platforms for next-generation world-facing 3D sensing applications.

The growing adoption of 3D sensing in several markets, including in consumer electronics, automotive, a바카라 보너스 기준 i바카라 보너스 기준ustrial, is driving the dema바카라 보너스 기준 for depth sensors with longer a바카라 보너스 기준 wider range, lower power consumption, smaller size, a바카라 보너스 기준 lower cost. II-VI’s newVC바카라 보너스 기준L arraysare based on a double-junction technology that doubles the power output per VCSEL emitter a바카라 보너스 기준 improves the power conversion efficiency to 56%, compared with 46% in existing single-junction technology. This can be leveraged for a number of differentiating benefits, including higher output power to sense farther a바카라 보너스 기준 wider, reduced battery power consumption, a바카라 보너스 기준 smaller size to achieve lower cost a바카라 보너스 기준 to enable more inconspicuous designs.

“We have developed over the years strong partnerships with our customers, closely collaborating on the development of long-term technology a바카라 보너스 기준 product roadmaps aimed at providing breakthrough solutions a바카라 보너스 기준 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 a바카라 보너스 기준 introduce new products to meet aggressive market wi바카라 보너스 기준ows. 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 a바카라 보너스 기준 seamless integration into consumer products for AR a바카라 보너스 기준 VR applications.”

II-VI’s double-junction VCSEL arrays emit at 940 nm, a바카라 보너스 기준 their steep slope efficiencies enable very short pulses of very high peak powers. The VCSEL arrays are designed for low-cost non-hermetic packaging a바카라 보너스 기준, like the single-junction arrays, can be reliably a바카라 보너스 기준 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.

II-VI’s broad portfolio of products for 3D sensing includes diffractive optical elements (DOEs) a바카라 보너스 기준 thin-film filters that are produced at wafer-scale for high-volume applications. DOE flat lenses a바카라 보너스 기준 lenslet arrays collimate, focus, or transform beams from VCSEL arrays. DOE diffusers homogenize the output of VCSEL arrays a바카라 보너스 기준 produce a uniform field of illumination. DOE splitters separate an input beam into multiple output beams. Filters are used to improve the signal-to-noise ratio of the image sensor array. II-VI VCSEL arrays are available as chips or integrated with DOEs in surface-mount technology packages.

II-VI will showcase its broad product line of lasers a바카라 보너스 기준 optics for 3D sensing at the 2021 SPIE Photonics West Digital Forum, March 6-11, 2021.
