Home / New Vertical Cavity Surface Emitting Laser
The surface emission from a bulk semiconductor at ultra-low temperature and magnetic carrier confinement was reported by Ivars Melngailis in 1965. The first proposal of short VCSEL was done by Kenichi Iga of Tokyo Institute of Technology in 1977. Contrary to the conventional Fabry-Perot edge-emitting semiconductor lasers, his invention comprises a short laser cavity less than 1/10 of the edge-emitting lasers vertical to a wafer s. The ams OSRAM VCSEL (Vertical-cavity surface-emitting laser) technology includes the epitaxial structure and chip design, epitaxial growth, front- and back-end processing, packaging and advanced testing and simulations. The research project "Komplex-gekoppelte vertikal-emittierende Hybrid-Mikrokavitätslaser mit organischen, aktiven Halbleitermaterialien für den UV-Bereich" 1, which is funded by the Deutsche Forschungsgemeinschaft (DFG) is realizing laser-structures, that face the mentioned challenges.
