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. ... -
Focused-ion-beam nanostructuring of Al2O3 dielectric layers for photonic applications
Ay, Feridun; Worhoff, Kerstin; de Ridder, Rene M.; Pollnau, Markus (IOP Publishing LTD, 2012)In this work, we report on utilization and optimization of the focused-ion-beam technique for the fabrication of nanostructures on Al2O3 waveguides for applications in integrated photonic devices. In particular, the ...
