Integrated Coherent Receiver
Neophotonics has announced the initial availability of its Integrated Coherent Receiver (ICR) for 100 and 40Gb/sec transmission systems.
The ICR is an integrated intradyne receiver based on Neophotonics' Photonic Integrated Circuit (PIC) technology.
This device provides advanced demodulation to analyse the state of polarisation and optical phase of a phase-modulated signal relative to an externally supplied optical reference.
This enables recovery of the phase-polarisation constellation of 100Gb/sec 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 32gbaud data rates.
A second version performs the same function for 40Gb/sec applications.
In addition to the ICR, Neophotonics currently offers 90deg Hybrid Coherent Mixers and DQPSK Demodulators based on PIC technologies.
The 90deg 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.
