NeoPhotonics announces integrated coherent receiver (ICR) for 100 Gbps coherent transmission systems

ECOC 2010, TORINO, ITALY: NeoPhotonics 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.

”We are pleased to enter the production phase on our 100Gbps Integrated Coherent Receiver. The ICR is an important element in enabling ultra high speed network links, and NeoPhotonics is committed to a goal of meeting customer requirements for performance and availability throughout the ramp up in deployment of 100 Gbps DWDM transmission equipment,” said Tim Jenks, chairman and CEO of NeoPhotonics.

NeoPhotonics’ ICR supports the requirements of the OIF* 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, enabling recovery of the phase-polarization constellation of 100 Gbps Dual Polarization Quadrature Phase Shift Keyed (DP-DQPSK) 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 utilizes hybrid photonic integration to achieve the high performance required for 100 Gbps applications. 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,” said Ferris Lipscomb, Vice President of Marketing at NeoPhotonics.
