TLDR
Electrically pumped lasing from Germanium-on-Silicon pnn heterojunction diode structures is demonstrated and a Germanium gain spectrum of nearly 200nm is observed.Abstract:
Electrically pumped lasing from Germanium-on-Silicon pnn heterojunction diode structures is demonstrated. Room temperature multimode laser with 1mW output power is measured. Phosphorous doping in Germanium at a concentration over 4x1019cm-3 is achieved. A Germanium gain spectrum of nearly 200nm is observed.read more
