Enhanced photoluminescence from germanium-based ring resonators
Peng Huei Lim, Yosuke Kobayashi, Shinya Takita, Yasuhiko Ishikawa, and Kazumi Wada
We report the enhancement of direct bandgap emission from germanium ring resonators based on silicon-on-insulator (SOI). As a consequence of their strong confinement, a record quality factor (Q) of 620 is obtained that is an order of magnitude higher than that previously characterized for crystallin ... [Appl. Phys. Lett. 93, 041103 (2008)] published Tue Jul 29, 2008.
