Vcsel definition

A laser with the lasing cavity running vertically through the layers of the semiconductor chip, which is mirrored at the bottom in order to maximize signal emission power at the top surface.VCSELs have capabilities somewhere between LEDs and other lasers. VCSELS have a spectral width somewhere between the two.VCSELs can couple effectively to a multimode fiber (MMF) with a narrower core than LEDs (50 microns versus 62.5 microns), but not as narrow (5
