Multi-level BPSK phase and power sequence (upper), constellation with transitions and tributary eye (lower) of the generated 80Gb/s sign[/caption]
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.
