NeoPhotonics launches integrated coherent receiver (ICR) for 100 Gbps and 40 Gbps coherent transmission systems

MARCH 23, 2010 NeoPhotonics introduced its Integrated Coherent Receiver (ICR) for 100 Gbps and 40 Gbps transmission systems. The ICR is an integrated intradyne receiver based on NeoPhotonics’s photonic integrated circuit (PIC) technology.

MARCH 25, 2010 NeoPhotonics introduced 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-QPSK) 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.

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)
