80Gb/s multi-level BPSK experiment with an InP-monolithic source based on prefixed optical phase switching

Improved-speed full-monolithic BPSK transmitter based on prefixed phase switching by fast Electro-Absorption Modulators has been realized on InP using a Selective Area Growth integrating circuit technology. It has been used in 80Gb/s multi-level BPSK format modulation experiments. Simplicity, speed scalability, ultra-small footprint and low power drive of the monolithic circuit are attractive for advanced format migration towards low-cost applications.
