Operating Principles of VCSELs - Uni Ulm
www.uni-ulm.deness. Metal organic chemical vapor deposition (MOCVD) or molecular beam epitaxy (MBE) are preferred for crystal growth. The pin-type doping conflg-uration is similar to conventional edge-emitting lasers (EELs). In the most simple device layouts, electric current is injected from ohmic contacts on the top epitaxial side and the backside of the ...
