Compact Hybrid-Integrated Multi-Wavelength O-Band Laser Source using Photonic Wire Bonding

We present an O-band multi-wavelength source for wavelength division multiplexed optical transceivers. The source architecture comprises a monolithic DFB laser array hybrid-integrated with a Si 3 N 4 star coupler via photonic wire bonds. The prototype source outputs an eight-wavelength comb into each of eight output fibers.
