Abstract :
Waveguide photodetector array was developed to be applicable to advanced modulation formats like QPSK, DPSK, and 16-QAM. The devices have spot-size converter for butt-coupling with PLC devices, and on-chip by-pass capacitor for DC bias. Coherent receiver made of the fabricated chips showed clear constellation for 30 Gbaud DP-QPSK OFDM signal.
