II‐VI Incorporated of Pittsburgh, Pennsylvania USA, announced the launch of its new edge emitting distributed feedback (DFB) laser diode for 3D sensing applications. The company points out that new applications in mixed and augmented reality are encouraging the rapidly increasing demand for semiconductor lasers integrated into consumer devices, including smartphones, smart glasses, and headsets.
II-VI’s 940 nm DFB Laser Diodes Offer More Than 500 mW Output
II-VI’s new 940 nm DFB laser diodes feature an output of more than 500 mW. According to the company, this power enables consumer devices to use the DFB laser diode to digitally reconstruct surrounding scenes in 3D with the help of the reflected laser light.
“This latest product leverages the deep expertise that we accumulated over our 20 year legacy in gallium arsenide lasers,” said Karlheinz Gulden, general manager, II-VI Laser Enterprise. “Our customers can rely on our global design and manufacturing teams that recently demonstrated our ability to rapidly scale production of a new laser for consumer electronics, to high volumes on a vertically integrated 6 inch gallium arsenide technology platform.”
DFB Laser Diodes Customizable
II-VI says its DFB laser diodes can be customized to achieve the optimum output power for the application. Engineering sample quantities are currently available for evaluation and design-in, as assemblies on ceramic carriers or in die form.
The new laser adds to II-VI’s portfolio of products for sensing including vertical cavity surface emitting lasers (VCSELs) for proximity sensing and thumb navigation, as well as VCSEL arrays for 3D sensing. The company’s product portfolio for sensing applications also includes low angle shift filters that select the reflected laser light over a wide field of view and reject other light to improve camera sensitivity.
