项目摘要

Photonic ATM switching systems should be in service at the beginning of the 21st century. For this target, photonic AMC is believed as the most reasonable approach, which is a kind of connector to realize a huge scale of ATM switching system by combinig AHM (ATM Virtual Circuit Handling Module). Our proposal of Multi-fold OFDM Self-Routing ATM Switching System is promising for photnic AMC.[1, 2] One of the important issue in realizing photonic AMC is how to realize photnic ATM cell buffer memory. In this project, one chip photonic ATM cell buffer memory is proposed and demonstrated in a mock discrete model[3].The basic structure of one chip cell buffer is based on PLC hybrid integration module including a photonic loop, WDM DEMUX and wavelength converters. An AWG DEMUX on PLC and three sets of wavelength converters using 2.5 Gb/s DFB/APD tranciever modules were combined to the mock discrete model of cell buffer, which demonstrated three WDM ATM cells storage at bit rate of 150 Mb/s. Tunable Laser Source HP8168B was used for input photonic ATM cell generation. We also analyzed Multihop Photonic AMC to propose Mach-Zenhder Lattice optical circuits for wavelength routers, which is improved in passband characteristics than AWG routers[5].

光子ATM交换系统将在世纪开始投入使用。光子AMC被认为是实现这一目标的最合理的途径，它是一种通过结合ATM虚电路处理模块（AHM）来实现大规模ATM交换系统的连接器。本文提出的多路OFDM自路由ATM交换系统在光电子AMC系统中具有很好的应用前景。[1，2]实现光子AMC的一个重要问题是如何实现光子ATM信元缓存。在这个项目中，提出了单片光子ATM信元缓冲存储器，并在模拟离散模型中进行了演示[3]。单片信元缓冲器的基本结构是基于PLC混合集成模块，包括一个光子环路，WDM DEMUX和波长转换器。将一个基于PLC的AWG DEMUX和三组采用2.5Gb/sDFB/APD收发模块的波长转换器组合成信元缓冲器的模拟离散模型，实现了150 Mb/s速率下三个WDM ATM信元的存储。可调谐激光源HP 8168 B用于输入光子ATM信元生成。我们还分析了多跳光子AMC，提出了用于波长路由器的Mach-Zenhder格型光电路，其通带特性比AWG路由器有所改善[5]。
