[advertise]广告[/advertise]San Jose, Calif. – September 18, 2009 – NeoPhotonics is announcing next week, at the European Conference and Exhibition on Optical Communication (ECOC)in Vienna, the general availability and volume shipment of its “photonic integrated circuit” (PIC) based Coherent Mixer for 40 and 100 Gbps optical transmission systems. Coherent mixers enable ultra high-rate optical transmission by revealing additional information about the amplitude and phase of the received optical signal over traditional intensity-level receivers, allowing transmission of multiple bits in each optical data pulse. Specifically, the Coherent Mixer product 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 for Dual Polarization Quadrature Phase Shift Keyed (DP-QPSK) data transmission. The NeoPhotonics Coherent Mixer requires no power, operates across the C or L band and is based on planar integration, utilizing high volume semiconductor production methodologies. At the same time, NeoPhotonics announced the initial availability of its demodulator for Differential Quadrature Phase Shift Key (DQPSK) data transmission. NeoPhotonics’ DQPSK demodulator consists of two PIC integrated Delay Line Interferometers (DLIs), providing in-phase and quadrature analysis of differentially phase-encoded signals. To accommodate the unpredictable and varying nature of the received signal polarization, NeoPhotonics’ DQPSK demodulator has been optimized such that the performance exhibits extremely low sensitivity to polarization variations. “Our photonic integrated circuit design and fabrication capabilities have enabled us to achieve both the high optical performance required for these products and to ramp production volumes in record time. Only photonic integrated circuits provide the high performance, compact size, temperature range and volume production capability required for these next generation products,” said Wupen Yuen, Ph.D., Vice President of Engineering for NeoPhotonics. NeoPhotonics is exhibiting at ECOC (stand 613 in the Austria Centre, September 21 – 23) the new products described above as well as the industry's most complete portfolio of MEMS and PIC (photonic integrated circuit) based optical components and broad line of telecom transceiver products in SFF, SFP and XFP form factors. In addition, Dr. Tony Ticknor, Director of R&D at NeoPhotonics, will provide a presentation on “PLC-based Hybrid Integration Devices” in the Workshop entitled “Monolithic and Hybrid Photonic Integrated Transceivers for Advanced Modulation Formats” at ECOC on Sunday, September 20 at 2:30 pm.
