We reported the first hybrid III-V/Si integrated QPSK wavelength-tunable transmitter providing high-speed (>23GHz) and low Vp (~1.3V). 80 Gbit/s PDM-QPSK signal transmission over 100 km with such integrated hybrid transmitter as well as a fully packaged silicon-based coherent receiver is demonstrated.
