100Gbps Coherent DP-QPSK Receiver, PicoMetrix CR-100D, PBS and 90Deg. Hybrid Integrated
The coherent receiver module CR-100D consists of an integrated polarization beam splitter and four balanced photo-receivers monolithically integrated with optical 90° hybrids. The receiver is a fully differential optical front-end suited for 100 Gbit/s DP-QPSK applications featuring high linearity and high common mode rejection ratio. The optical 90° hybrids demodulate the I/Q incident signal for each respective polarization state using external reference oscillator laser sources. The mixing products are detected by PIN-photodiodes and amplified by trans-impedance amplifiers (TIA) with linear transfer characteristics.
