Finisar announced its participation at Sensors Expo with several demonstrations and product displays. Finisar will demonstrate VCSEL arrays and Diffractive Optics Technology used in a wide range of 3D depth-sensing and Infrared (IR) Imaging applications, such as 3D facial recognition in consumer mobile devices. Finisar will also have samples of a highly integrated 1550nm coherent transmitter and receiver module for next-generation LiDAR applications. VCSEL Technology Demonstration 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 brings several exciting advantages including high output power, high uniformity across an extended source area, stable wavelength across temperature, and high reliability, which are important for both IR Illumination and stringent automotive applications. Finisar’s VCSEL expertise stems from over two decades of research, design, and manufacturing innovation. Diffractive Lenses and Beam Converters Demonstration: 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 550 °C. LiDAR Coherent Optical Engine Display: Finisar will showcase 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. During Sensors Expo, Finisar will also display several partner reference designs leveraging VCSEL technology.
