NeoPhotonics Launches Integrated Coherent Receiver (ICR) For 100 Gbps and 40 Gbps Coherent Transmission Systems

Supports  Expected Requirements of Emerging Standard Agreements for 100G Integrated Coherent Receivers

San Diego, CA – March 22, 2010 – NeoPhotonics today announced the initial availability of its Integrated Coherent Receiver (ICR) for 100 Gbps and 40 Gbps transmission systems.  The ICR is an integrated intradyne receiver based on NeoPhotonics’ Photonic Integrated Circuit (PIC) technology. 

This 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.  In addition, 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.  A second version performs the same function for 40 Gbps applications.

”We are pleased to add the ICR to our existing line of PIC products for high speed transmission systems.   We utilize our hybrid PIC technology to combine an integrated dual 90°Hybrid Coherent Mixer with four balanced photodiodes and the requisite linear amplifiers in a single compact package,” said Tim Jenks, Chairman and CEO of NeoPhotonics.

“NeoPhotonics is actively contributing to developments in the Optical Internetworking Forum (OIF) 100G project, particularly with respect to Integrated Photonics Receiver,” said Wupen Yuen, Vice President of Research and Development at NeoPhotonics.  “NeoPhotonics is also participating in the OIF Product Showcase* for 100G components and the NeoPhotonics ICR may be seen displayed there*,” continued Dr. Yuen.

In addition to the ICR, NeoPhotonics currently offers 90°Hybrid Coherent Mixers and DQPSK Demodulators based on PIC technologies.  The 90°Hybrid Coherent Mixer provides the demodulation function of the ICR, requires no electrical power, operates across the C or L band and is designed to be used with external photo-receivers.  NeoPhotonics’ DQPSK demodulator consists of two Delay Line Interferometers (DLIs) and provides in-phase and quadrature analysis of a phase-encoded signal. 

NeoPhotonics is showcasing its products this week at the OFC/NFOEC Conference and Exposition in San Diego (March 23 – 25, in booth 1125) 

*The OIF is sponsoring a Product Showcase at OFC/NFOEC 2010 to display components, modules, and/or other hardware supporting the OIF’s 100G project focused on Integrated Photonics Transmitters and Receivers. OIF member companies and their products can be viewed at the OIF booth # 3041. For more information about the OIF, visit
