WHAT DOES VCSEL MEAN?

As well as the high beam top quality of reduced-power VCSELs, a very important component would be the reduced beam divergence, compared with that of edge-emitting laser diodes, and also the symmetric beam profile.VCSELs for wavelengths from 650 nm to 1300 nm are generally dependant on gallium arsenide (GaAs) wafers with DBRs fashioned from GaAs a
