NeoPhotonics introduces integrated coherent receiver

NeoPhotonics of San Jose, CA, USA has 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 the firm’s Photonic Integrated Circuit (PIC) technology.

The ICR 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, it 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, VP of Research and Development at NeoPhotonics.

The firm is showcasing its products this week at the OFC/NFOEC conference in San Diego, CA, USA, where the OIF is sponsoring a Product Showcase 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.
