Finisar to demo VCSELs at Sensors Expo 2018
Finisar has announced its participation at Sensors Expo (San Jose McEnery Convention Center on June 27th and 28th) with several demonstrations and product displays.
Finisar will demonstrate VCSEL arrays and diffractive optics used in a wide range of 3D depth-sensing and Infrared (IR) Imaging applications, such as 3D facial recognition in consumer mobile devices. The company will also have samples of a highly integrated 1550nm coherent transmitter and receiver module for next-generation LiDAR applications.
Finisar will have a live demonstration of IR Illumination for 3D sensing using VCSELs and Diffractive Optics technology. The demonstration will show IR light-field measurements made in real-time for 3D Time-of-Flight (ToF) and 2D IR Imaging applications.
"VCSEL technology is now being deployed in a wide range of exciting applications from biometric authentication, to 3D mapping for augmented reality, to automotive LiDAR. We're excited to be at the forefront of this technology in both R&D and manufacturing," said Craig Thompson, VPt of marketing and business development for 3D Sensing at Finisar.
Finisar will also demonstrate all-dielectric diffractive lenses and beam converters which use a proven Deep UltraViolet (DUV) photolithography patterning process. These products have several applications including aberration corrected microlenses, top hat generators, phase converters, and computer-generated holograms. The diffractive elements are etched directly into a substrate and contain no organic materials, which allows them to withstand high optical power and extreme temperatures up to 550degC.
Finisar will show a LiDAR coherent optical engine that is designed to enable long-distance resolution up to 300 meters for applications such as autonomous driving vision systems. The small package integrates a wavelength-tunable laser, a transmitter phase modulator, and a coherent receiver. The laser can be tuned across 4 THz, allowing solid state beam steering to replace less reliable rotating mirrors and microelectromechanical systems (MEMS). The phase modulator and coherent detection enable the distance and velocity of an object to be determined from a single scan using the Doppler effect.
