Demonstration of an On-Chip III-V/Si Hybrid Semiconductor Optical Amplifier for Photonics Integration

We demonstrate a III-V/Si hybrid semiconductor optical amplifier at 1284 nm with on-chip gain >20 dB, output power >50 mW, internal noise-figure <;7 dB, 3 dB bandwidth >40 nm, and amplification of 25 Gbps NRZ data with <;1 dB power penalty at 10
