Finisar demonstrating VCSEL arrays and diffractive optical elements for 3D sensing at Photonics West

In booth #4045 at the SPIE Photonics West 2019 event in San Francisco (5-7 February), fiber-optic communications component and subsystem maker Finisar Corp of Sunnyvale, CA, USA is demonstrating vertical-cavity surface-emitting laser (VCSEL) arrays used in depth-sensing applications, such as 3D facial recognition in consumer mobile devices. It is also displaying its line of diffractive optical elements, demonstrating WaveSource technology, and introducing a new high-speed photodetector.

“Finisar is excited to be part of this surge in adoption of laser and optics technology for sensors in smartphones, automobiles, and smart home appliances, amongst dozens of other applications,” says Craig Thompson, VP of new markets. “VCSELs are a key enabler in the broad use of 3D sensing and imaging technology, and the electronics industry is starting to recognize this,” he adds.

Finisar’s demonstrations at Photonics West include the following:

  • A 3D camera, utilizing VCSEL technology as the infrared (IR) source, to demonstrate 3D depth sensing. Designed by Finisar partner Gener8, the 3D camera provides an accurate, high-resolution and real-time 3D ‘depth map’ of the scene, allowing a consumer device or a car to see in 3D, recognize movements or ‘gestures’ and map objects in detail. The set-up will allow attendees to interact with the live camera;
  • An active demonstration of diffractive optical elements (DOEs) that shape, steer and control the light output from a laser (e.g. VCSEL) in a 3D sensor. Finisar is showing various functions using a beam profiler;
  • Finisar’s WaveSource laser unit demonstrating high-speed programmable wavelength tuning with support of a WaveAnalyzer 1500S optical spectrum analyzer;
  • A display of the firm’s product line of ultra-high-speed photodetectors, including a 70GHz dual-wavelength device, useful in coherent test & measurement systems and ultra-high RF output power photodetectors suitable for microwave photonics and Radio over Fiber applications.

In addition, on 7 February (at 11am in Room 159, South Upper Mezzanine) Hao Chen, principal engineer for 3D Sensing products, is giving the presentation ‘Cost-effective monolithically integrated surface grating for polarization-stable VCSELs’, describing a shallow semiconductor grating that has been developed as an add-on feature of Finisar’s VCSEL product family for low-cost yet highly effective polarization control in a range of different sensing applications.
