We numerically investigate the potential of Al2O3:Er3+ active slot waveguides for realizing small-form factor lasers on SOI. Based on recent technological improvements in the reliable and low-cost fabrication of alumina doped with high Er3+ concentration, we point out the possibility of realizing silicon compatible emitters at 1.55 um, optically pumped at 1480nm with a few mW threshold pump power.

Abstract
We numerically investigate the potential of Al2O3:Er3+ active slot waveguides for realizing small-form factor lasers on SOI. Based on recent technological improvements in the reliable and low-cost fabrication of alumina doped with high Er3+ concentration, we point out the possibility of realizing silicon compatible emitters at 1.55 um, optically pumped at 1480nm with a few mW threshold pump power.
