NeoPhotonics launches coherent receiver with integrated polarizing beam splitter

At this week’s Optical Fiber Communication Conference and Exhibition/National Fiber Optic Engineers Conference (OFC/NFOEC 2011) in Los Angeles (8–10 March), NeoPhotonics Corp of San Jose, CA, USA, which designs and manufactures photonic integrated circuit (PIC)-based modules and subsystems for bandwidth-intensive, high-speed communications networks, has launched a PIC-based integrated coherent receiver (ICR) for 40 and 100Gbps dense wavelength division multiplexing (DWDM) transmission systems that incorporates an integrated polarizing beam splitter (PBS). The firm previously launched its initial ICR (without integrated PBS) at OFC/NFOEC 2010 in San Diego last March.

The new ICR is designed to eliminate the need for system designers to place a PBS externally, decreasing circuit board footprint requirements. The product supports the OIF Implementation Agreement for Integrated Dual Polarization Intradyne Coherent Receivers. The ICR is designed to provide advanced demodulation to analyze the state-of-polarization and optical phase of a phase-modulated signal relative to an externally supplied optical reference signal, enabling recovery of the phase-polarization constellation of 100Gbps dual-polarization quadrature phase-shift keyed (DP-DQPSK) format signals.

“Key benefits of the NeoPhotonics ICR with an integrated PBS include that it allows customers to eliminate an external beam splitter from line-cards and simplifies fiber routing,” says chairman & CEO Tim Jenks. “By using our photonic integration technology, we are able to integrate the PBS without changing the ICR form factor, streamlining the design-in process for our customers.”
NeoPhotonics also offers PIC-based 90° hybrid coherent mixers and DQPSK demodulators.

*On Monday at OFC/NFOEC, NeoPhotonics’ chairman & CEO Tim Jenks, together with a panel of industry peers, discussed the topic ‘Where is the Optical Components Market Going?’ at the 2011 OSA Executive Forum. Panelists evaluated technology developments, evolving customer needs, capital requirements and other elements that will impact business models in the reinvigorated optical components sector.

Also, at OFC/NFOEC today, David Piehler, Access Technology director at NeoPhotonics, is giving two presentations, including an invited talk, on topics related to optical access networks:

• ‘Next-Generation Components for Optical Access Networks’;
  
• ‘Implementing High [>2048] Split Ratios in any PON’.

NeoPhotonics is also showcasing a complete line of PIC-based and other products for access, metro, long-haul and other applications in booth 1025.
