HIGH POWER VCSEL OPTIONS

Along with the high beam high-quality of very low-power VCSELs, a crucial element will be the small beam divergence, when compared with that of edge-emitting laser diodes, along with the symmetric beam profile.VCSELs for wavelengths from 650 nm to 1300 nm are typically based upon gallium arsenide (GaAs) wafers with DBRs shaped from GaAs and alumi
