NeoPhotonics Develops Coherent Receiver with Polarizing Beam Splitter

NeoPhotonics introduced an Integrated Coherent Receiver (ICR) for 40 and 100 Gbps DWDM transmission systems that incorporates an integrated polarizing beam splitter (PBS), eliminating the need to place a PBS externally.

The NeoPhotonics ICR is designed to provide advanced demodulation to analyze the state-of-polarization and optical phase of a phase-modulated signal relative to an externally supplied optical reference signal, enabling recovery of the phase-polarization constellation of 100 Gbps Dual Polarization Quadrature Phase Shift Keyed (DP-DQPSK) format signals.

"Key benefits of the NeoPhotonics ICR with an integrated PBS include that it allows customers to eliminate an external beam splitter from line cards and simplifies fiber routing," said Tim Jenks, Chairman and CEO of NeoPhotonics. "By using our photonic integration technology, we are able to integrate the PBS without changing the ICR form factor, streamlining the design-in process for our
