A new compact coherent receiver module comprising a micro-optic polarization beam splitter and two InP-based 90 hybrids with integrated photodiodes is characterized at 112 Gbit/s DP-QPSK. A penalty of only 1.3 dB in OSNR sensitivity at a BER of 103 compared to theory was obtained at C-band wavelengths.
