Core components of intelligent information world

VCSEL (Vertical Cavity Surface Emitting Laser),is a key device in 3D imaging module, which has the advantages of high photoelectric conversion efficiency, easy integration of two-dimensional light-emitting array, low cost, small divergence angle, etc. It is widely used in 3D recognition sensing, optical communication, optical interconnection and other fields.

Device Introduction

VCSEL is a semiconductor laser that, as the name, shoots perpendicular to the top

  • The luminescent layer is called multiple quantum well (MQW), in which MQW composed of InGaAs and AlGaAs is the most suitable

    *The ratio of indium (in) can determine the wavelength of laser emission

  • P-DBR and n-dbr are the upper and lower parts of MQW emitting layer, which are used to screen out the "pure" light of specific wavelength. Since the direction of the outgoing light is usually at the top, a layer of substrate is needed at the bottom
