Low-Threshold Pump Power and High Integration in Al O  : Er ^ Slot Waveguide Lasers on SOI

We numerically investigate the potential of Al 2 O 3 :Er 3+ active slot waveguides for realizing small-form factor lasers on silicon-on-insulator. Based on recent technological improvements in the reliable and low-cost fabrication of alumina doped with high Er 3+ concentration, we point out the poss...

Zusammenfassung:We numerically investigate the potential of Al 2 O 3 :Er 3+ active slot waveguides for realizing small-form factor lasers on silicon-on-insulator. Based on recent technological improvements in the reliable and low-cost fabrication of alumina doped with high Er 3+ concentration, we point out the possibility of realizing silicon compatible emitters at 1.55 μm, optically pumped at 1480 nm with a few milliwatts threshold pump power.
