III-V-on-Si DFB Laser With Co-Integrated Power Amplifier Realized Using Micro-Transfer Printing

A C-band III-V-on-Si distributed feedback (DFB) laser with co-integrated power amplifier was realized using micro-transfer printing. The DFB laser exhibits single mode operation around 1540 nm at 20 °C. By driving the DFB laser and co-integrated power amplifier simultaneously, up to 14 dBm waveguide-coupled output power with over 28 dB side mode suppression ratio was achieved at an overall bias current of 270 mA.
