Abstract :
Recent progresses on monolithic InP integration are presented for achieving high-performance transmitters for cost-sensitive metropolitan networks. We demonstrate the generation of advanced modulation format using two types of integrated transmitters with prefixed optical phases. Complex modulation formats are generated with constellations exploiting the whole complex plane such as BPSK, quadrature phase-shift keying, N-QIM, and 2ASK-2PSK modulation. We achieve data rate up to 224 Gb/s using 2ASK-2PSK modulation with polarization division multiplexing. Finally, we assess its suitability for metropolitan networks with a large number of cascaded nodes.
