NeoPhotonics announces general availability of Integrated Coherent Receiver for 100Gbps coherent transmission

At this week’s European Conference and Exhibition on Optical Communications (ECOC 2010) in Turin, Italy (20–22 September), NeoPhotonics Corp of San Jose, CA, USA, vertically integrated manufacturer of photonic integrated circuit (PIC) based components, modules and subsystems for telecoms networks, is announcing general availability of its Integrated Coherent Receiver (ICR) for 100Gbps DWDM transmission systems, an integrated intradyne receiver based on its PIC technology. Initial availability was previously announced at March’s Optical Fiber Communication Conference & Exposition and National Fiber Optic Engineers Conference (OFC/NFOEC 2010) in San Diego.

“The ICR is an important element in enabling ultra-high-speed network links, and NeoPhotonics is committed to a goal of meeting customer requirements for performance and availability throughout the ramp up in deployment of 100Gbps DWDM transmission equipment,” says chairman & CEO Tim Jenks.

The ICR supports the requirements of the Optical Internetworking Forum (OIF) Implementation Agreement on 100G Integrated Polarization Intradyne Coherent Receivers. The 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 100Gbps dual-polarization quadrature phase-shift keyed (DP-DQPSK) format signals. 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.

“NeoPhotonics utilizes hybrid photonic integration to achieve the high performance required for 100Gbps applications,” says VP of marketing Dr Ferris Lipscomb. “NeoPhotonics hybrid PICs use 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, improving both performance and yield,” he claims.

As part of the ECOC ‘Market Focus’ program, Lipscomb is giving the presentation ‘Photonic Integrated Circuit Based Coherent Receivers Represent A New Paradigm For Optical Components’ covering the relationship between PIC technology and advanced data encoding (Monday, 20 September, 3:35 pm).

In addition to the ICR, NeoPhotonics currently also offers 90° hybrid coherent mixers and DQPSK demodulators based on PIC technologies.
