SAN JOSE, Calif. -- NeoPhotonics Corporation, a leading supplier of integrated optical, planar lightwave circuit (PLC) modules for optical networking applications, will present at next week’s OFC/NFOEC 2005 conference in Anaheim a series of papers describing technological advancements critical to the realization of next-generation reconfigurable metro and long-haul networks, especially in the domain of reconfigurable optical add/drop multiplexers, or ROADMs. NeoPhotonics also will exhibit these advanced technologies in booth 1657.

Future optical systems will be constructed out of integrated “optical systems on a chip,” in much the same manner that electronic ICs replaced transistors. For this to happen, the performance of the individual integration building blocks must be competitive with discrete solutions and the yield of each element must be very high so that the cost advantages of integration are realized. The papers presented next week will describe how NeoPhotonics has put into place the building blocks necessary for large scale PLC integration of optical functions.

For example, NeoPhotonics has demonstrated a fully integrated, single chip, 32-channel 100 GHz blocker packaged in a standard AWG MSA package (150mm x 65mm x 11 mm) with a throughput loss of only 5 dB. This device integrates more than 100 optical functions on a single chip. NeoPhotonics also will report the integration of an 8-channel “colorless” ROADM on a single chip, as well as a single-chip 8 channel “colorless” monitored Variable Optical Attenuator Multiplexer (VOA-MUX). To enable these devices, NeoPhotonics also has achieved on-chip temperature control to thermally manage multiple active devices on a chip and a very wide band AWG that allows cascading of up to 16 nodes in a metro ring.

The papers referenced above are as follows (locations in Anaheim Convention Center unless otherwise noted):

  • OTuD1 Multi-Function Integrated AWG Devices, Jane Lam, Alice Liu, Ming Yan. (Session begins 2 p.m. on March 8th in Ballroom D.)

  • JWA73 Low-Loss PLC Integration of Wavelength Blockers and Monitored VOA-Multiplexers for ROADM Applications, Alice Liu, Jane Lam, M. Yan. (Session begins 6 p.m. on March 9th at the Hilton Anaheim, California Pavilion.)

  • NThL3 Efficient Passive and Active Wavelength-Stabilization Techniques for AWGs and Integrated Optical Filters, A. Ticknor, B. McGinnis, T. Tarter, M. Yan. (Session begins 11 a.m. on March 10th in Room 210 C-D).

  • OTuD7 Individual Control of Multiple AWGs on a Monolithic Chip Using Integrated Thin Film Heaters and Sensors, Ming Yan, Calvin Ho, Hao Xu, Wen Li, Thomas Tarter. (Session begins 2 p.m. on March 8th in Ballroom D.)

In addition, Chris Pfistner, Director of Global Access Business for NeoPhotonics, will moderate the panel: MW Broadband Access: FTTP Is Changing the Game. (Session begins 3 p.m. on March 8th in Exhibit Hall D.)
