NIR VCSELs are proliferating from Datacom to Consumer Electronics and Automotive Applications. 3D object detection
and imaging at distances from 1 to 100m is in the focus. VCSEL arrays for Flash LiDARs are considered or already in use
for in-cabin/exterior-to-car detection, ADAS, gesture recognition, drones, robotics etc. In this work, we propose high peak
power NIR VCSEL arrays with large range of field of view (FOV). The effective refractive index (neff) of the core and
clad sections of the VCSEL structure based on industrial standard III-V processing is adapted to these applications.
Controlling the transverse lasing modes, beam divergences as large as 46° can be achieved. Using the symmetric radiation
profile and wide FOV, segmented VCSEL arrays offer a wide range of object detection applications, needing in addition
adapted driver ICs and angled diffusers.
