TORINO, Italy, Oct. 7, 2010 — For 100-Gb/s dense wavelength division multiplexing coherent transmission systems, NeoPhotonics Corp. has announced the general availability of its integrated coherent receiver. The integrated intradyne receiver is based on proprietary photonic integrated circuit technology.

The device supports the requirements of the Optical Internetworking Forum’s Implementation Agreement on 100-Gb/s Integrated Polarization Intradyne Coherent Receivers. It performs 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-Gb/s dual-polarization quadrature phase-shift keyed format signals. It incorporates four sets of high-sensitivity balanced photodiodes with four differential linear amplifiers to provide four output channels at 32 Gbaud data rates.

The company’s hybrid photonic integrated circuit technology uses 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.
