Hybrid integration on SOI motherboards is a versatile technology to provide solutions for the detection of PSK modulated data signals. We have shown assembly and successful testing of a 40 Gbps DPSK receiver comprising a waveguide integrated demodulator on SOI and flip-chip integrated InP-based photodetectors. Coherent detection with 4x4 MMIs for 90° hybrids was investigated using the same integration platform. Low phase deviations and operation over the entire C-Band enable integrated solutions of QPSK detectors. Potential receiver bandwidths of > 40 GHz permit symbol rates of up to 57 Gbaud/s and receiver designs for 200 Gbps QPSK.
