Finisar Shows VCSEL Innovations at Photonics West


Highlighting market adoption of VCSEL technology for 3D Sensing

Finisar, a maker of optical communication components and VCSELs, has announced its participation at Photonics West with several new innovations highlighting the growth in optics technology in smartphones and automotive sensing. During the exhibition,

Finisar will demonstrate VCSEL arrays used in depth-sensing applications, such as 3D facial recognition in consumer mobile devices. The company will also display its line of diffractive optical elements, demonstrate WaveSource technology, and introduce a new high-speed photodetector. See these market-leading products and demonstrations in Finisar's booth at the San Francisco Moscone Center, February 5-7.

“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. VCSELs are a key enabler in the broad use of 3D sensing and imaging technology, and the electronics industry is starting to recognize this and the value that Finisar brings,” said Craig Thompson, VP of new markets, Finisar.

Finisar’s demonstrations at Photonics West 2019 will include the following:

A 3D camera, using VCSEL technology as the 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 will show 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 analyser;

A display of the company’s market-leading product line of ultra-high-speed photodetectors, including a 70GHz dual wavelength device, useful in coherent test and measurement systems and ultra-high RF output power photodetectors suitable for microwave photonics and Radio over Fiber applications.

In addition to these demonstrations, Hao Chen, principal engineer for 3D Sensing products at Finisar, will present 'Cost-effective monolithically integrated surface grating for polarisation-stable VCSELs' on February 7th. The presentation will describe a shallow semiconductor grating that has been developed as an important add-on feature of Finisar’s VCSEL product family for low-cost yet highly-effective polarisation control in a range of different sensing applications.
