NOT KNOWN DETAILS ABOUT VCSEL LASER

Due to brief resonator spherical-trip time, VCSELs is usually modulated with frequencies effectively during the gigahertz assortment. This makes them valuable as transmitters for optical fiber communications and for free-Place optical communications.VCSELs for wavelengths from 650 nm to 1300 nm are generally based on gallium arsenide (GaAs) wafer
