Erbium-doped spiral amplifiers with 20 dB of net gain on silicon

Vazquez-Cordova, Sergio A.; Dijkstra, Meindert; Bernhardi, Edward H.; Ay, Feridun; Worhoff, Kerstin; Herek, Jennifer L.; Pollnau, Markus (Optical Soc Amer, 2014)

Spiral-waveguide amplifiers in erbium-doped aluminum oxide on a silicon wafer are fabricated and characterized. Spirals of several lengths and four different erbium concentrations are studied experimentally and theoretically. ...
