VCSEL (Vertical Cavity Surface Emitting Laser) laser diodes have become increasingly popular in the telecommunications, sensing, LIDAR, and optical interconnect industries due to their high efficiency, low power consumption, and high-speed modulation…

What is a VCSEL? VCSEL stands for Vertical Cavity Surface Emitting Laser, in this case, the laser resonator is aligned to the orthogonal direction with respect to the plane of the semiconductor substrate to allow vertical emission of light. It…
