Vertical Cavity Surface Emitting Laser - Optical Fiber Data Transmission Accounts for Dominant Share by Application
Vertical Cavity Surface Emitting Lasers (VCSEL) are semiconductor lasers, or more precisely laser diodes with monolithic laser resonator, where the light emitted leaves the device in a perpendicular direction to the chip surface. This is in contrast to the conventional edge-emitting lasers where the beam is emitted by splitting the single chip out of the wafer. VCSELs have a number of advantages over its conventional counterparts. These include high compatibility with other circuitry and detectors, high reliability, scalability, package ability,...
