112-Gb/s InP DP-QPSK modulator integrated with a silica-PLC polarization multiplexing circuit

We fabricated an ultra-compact InP-based DP-QPSK modulator by the hybrid integration of an InP twin-IQ modulator and a PLC polarization multiplexing circuit for the first time. 112-Gb/s DP-QPSK modulation is successfully demonstrated.
