Full C-band 40-Gbit/s DPSK tunable transmitter module developed by hybrid integration of tunable laser and InP n-p-i-n Mach-Zehnder modulator

A 40-Gbaud tunable transmitter module was developed for the first time by the hybrid integration of a full C-band tunable laser and an InP Mach-Zehnder modulator. Wavelength-tunable chirpless 40-Gbit/s DPSK modulation was successfully demonstrated.
