Through co-design of a dual SiGe transimpedance amplifier and an integrated silicon photonic circuit, we realized for the first time an ultra-compact and low-power silicon single-polarization coherent receiver operating at 40 GBd. A bit-error rate of <3.8 x 10(-3) was obtained for an optical signal-to-noise ratio of 14 dB for QPSK modulation (80 Gb/s), and 26.5 dB for 16-QAM (160 Gb/s). We also demonstrate robust performance of the receiver over temperature and wavelength.
