We report on recent measurements of integrated coherent receiver modules for 100G Ethernet transport. In system experiments with up to 160-Gb/s PDM-QPSK signals and 224-Gb/s PDM-16QAM signals their potential for detection of high symbol rate signals and higher order modulation formats is demonstrated. Furthermore, a new fully integrated polarization-diversity coherent receiver module comprising a micro-optic polarization beam splitter and two InP-based 900 hybrids with integrated photodiodes is characterized using 112-Gbit/s PDM-QPSK signals.
