VCSEL Market: Pioneering Next-Gen Optical Technologies with Precision and Efficiency
The VCSEL (Vertical-Cavity Surface-Emitting Laser) market is experiencing rapid growth due to its crucial role in optical communication, sensing, and emerging 3D sensing applications. VCSELs are semiconductor lasers that emit light vertically from the surface of the chip, offering manufacturing advantages and superior performance compared to traditional edge-emitting lasers.
What is a VCSEL?
A Vertical-Cavity Surface-Emitting Laser (VCSEL) is a semiconductor laser diode that emits light perpendicular to the surface of the semiconductor wafer. Unlike conventional lasers that emit from the edge, VCSELs enable wafer-level testing, higher production yields, and easier integration into arrays for various applications.
