The ICR is an integrated intradyne receiver based on NeoPhotonics’ photonic integrated circuit (PIC) technology.

SEPTEMBER 20, 2010 -- NeoPhotonics has announced at the European Conference and Exhibition on Optical Communications (ECOC) the general availability of its Integrated Coherent Receiver (ICR) for 100-Gbps DWDM transmission systems. The ICR is an integrated intradyne receiver based on NeoPhotonics’ photonic integrated circuit (PIC) technology.

NeoPhotonics’ ICR is designed to support the requirements of the OIF’s Implementation Agreement on 100G Integrated Polarization Intradyne Coherent Receivers. The device provides advanced demodulation to analyze the state-of-polarization and optical phase of a phase-modulated signal relative to an externally supplied optical reference. This enables recovery of the phase-polarization constellation of 100-Gbps dual polarization quadrature phase-shift keying (DP-QPSK) format signals. The ICR incorporates four sets of high sensitivity balanced photodiodes with four differential linear amplifiers to provide four output channels at 32-Gbaud data rates.

NeoPhotonics’ hybrid PICs use planar glass waveguides for the coherent mixing function and semiconductor chips for the detectors and amplifiers, ensuring that each function is matched to the device and material, improving both performance and yield, according to the company.
