Introduction to VCSEL IR Laser Diode
VCSEL (Vertical - Cavity Surface - Emitting Laser) IR (Infrared) Laser Diodes are a type of semiconductor laser. Unlike traditional edge - emitting lasers, VCSELs emit light perpendicular to the wafer surface. This unique structure offers several advantages. Firstly, they have a circular output beam, which simplifies the optical coupling and system design. Secondly, they can be tested at the wafer - level, reducing the manufacturing cost and improving production efficiency.
Infrared VCSELs operate in the infrared wavelength range, typically from 780 nm to 1550 nm, and are widely used in various fields. In consumer electronics, they are used for facial recognition in smartphones, enabling quick and secure unlocking. In automotive, they are crucial components for LiDAR (Light Detection and Ranging) systems, which are essential for autonomous driving. They also find applications in data communication, medical devices, and industrial sensing.
