Vertical-Cavity Surface-Emitting Lasers (VCSELs) are semiconductor devices used in a variety of applications, such as optical data communication, sensing, and printing. VCSELs are semiconductor lasers that emit light perpendicular to the surface of the chip, rather than through a cleaved facet like traditional edge-emitting lasers. This makes them more efficient and cost-effective than edge-emitting lasers. VCSELs are used in a variety of applications, including optical data communication, sensing, and printing. They are also used in consumer electronics, such as smartphones, tablets, and laptops. VCSELs are becoming increasingly popular in the semiconductor industry due to their low cost, high efficiency, and small size. They are also being used in a variety of emerging applications, such as 3D sensing, LiDAR, and autonomous vehicles. Some of the major companies in the VCSEL market include Finisar, II-VI, Lumentum, and NeoPhotonics. Show Less Read more
