We demonstrated a semiconductor optical amplifier hybrid-integrated with a silica-based planar lightwave circuits. With deploying polarization diversity circuit, polarization dependent gain was reduced from 22.9 dB to 1.8 dB in C-band.

Optical amplifier will be required for advanced optical interconnect systems to compensate optical signal loss. We propose a hybrid integration of semiconductor optical amplifier with polarization diversity for low polarization dependent gain operation.

An 8 ch DFB-LD-PLC hybrid device was fabricated with high precision active alignment. The coupling loss between the DFB-LD and the PLC was 3.6 dB. All of 8 ch DFB-LDs oscillated appropriately.
