Abstract
A small footprint integrated optical amplifier on Silicon-On-Insulator (SOI) is proposed in this article. By using a membrane active waveguide the optical confinement is maximized, leading to a compact device with high gain. Furthermore, the device is optically pumped through the silicon waveguide layer to optimally use the pump light. We show 8 dB gain in pulsed regime in a 100 um long device using a peak pump power of only 4.5mW. This is an important step towards a CMOS-compatible optical amplifier for intra-chip optical interconnects. Related Research Topics
