Abstract
A novel waveguide shape is proposed to take advantage of the high index contrast in adhesively bonded III-V on Silicon-On-Insulator (SOI) waveguides for application in on-chip semiconductor optical amplifiers. By decreasing the effective index of the top contact layer, the confinement in the active region can be increased by 70%, boosting the achievable modal gain and reducing the required device length to achieve a certain gain. This technique could reduce the footprint of amplifiers, lasers and other active devices integrated on the SOI platform. Related Research Topics
