The new NeoPhotonics® ICR is designed to eliminate the need for system designers to place a PBS externally, decreasing circuit board footprint requirements. The product supports the OIF Implementation Agreement for Integrated Dual Polarization Intradyne Coherent Receivers*. 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 customers, concluded Mr. Jenks.
In addition to the ICR announced today, NeoPhotonics currently offers PIC-based 90° Hybrid Coherent Mixers and DQPSK Demodulators.
