Lumentum Operations LLC
Vertical Cavity Surface Emitting Lasers (VCSELs) revolutionized communications systems in the 1990s. As the technology improved, VCSELs began to be employed in sensing applications because of the inherent advantages VCSELs offered over LEDs and edge-emitting lasers. More recently, VCSEL arrays have revolutionized 3D sensing in many applications, including mobile devices, biometric identification, AR/VR, autonomous vehicles, and industrial systems.

Why VCSELs, and why now? This presentation explains how VCSELs started the next revolution in sensing; why VCSELs are leading 3D sensing’s progression into everyday lives; and where the technology and its applications will go in the future.
