可精细调控的集成化高速大容量光学缓存基础研究

With the rapid development of information communication technology, the bandwidth and data rate of network needs to improved to meet the increasingly requirements. The exchange rate of core nodes in optical network has become the most important factor which mainly determines the performance of optical network, in which data routing and buffering are the two key challenges. Electrical buffering technology has been unable to meet the requirements of large capacity and high-speed optical signal transmission, on the other hand, implementation of data buffering in the optical domain has many advantages, such as high-speed, electro-magnetic compatible, data format transparent and low-power consumption. In order to satisfy the urgent needs of optical buffer memory and solve a series of key issues, such as low-speed, small capacity and buffer time can not be accurately controlled, this project propose a novel integrated optical buffering technique with fine reconfigurability, high speed and large capacity. The proposed technique is to realize the integrated optical buffer long time high precision from two dimensions based on the controlling the cycle number and single cycle delay simultaneously. The key feature of this technique is an optical signal can be buffered with fine reconfigurability, high-speed and broad bandwidth, in addition the device can be photonic integrated in high density. The proposed optical buffer technology can be used not only in the field of optical communication, but also have potential applications in all-optical signal processing, phased array antenna, time domain spectrum decomposition and all-optical computing fields.

随着通信技术的飞速发展，速率和带宽成为光网络性能提升的关键瓶颈。核心节点处的交换速率成为光网络性能的最主要限制因素，包括数据的路由和缓存等。电缓存技术已经无法满足超大容量高速光信号交换的需求，而在光域进行数据的缓存具有速度快、电磁兼容性好、数据格式透明以及低功耗等优点。为了应对高性能光缓存的迫切需求，本项目针对光缓存技术依然存在的带宽不足以及延时时间长度与调控精细度之间无法同时满足的问题，提出了一种通过控制循环次数和单次循环延时两个维度调控实现长时间高精度的集成化光缓存的新方案，具有高精细调控、高速率调控、宽光谱调控和高密度集成等优点。本项目所提出的光缓存技术不仅在光通信领域，在全光信号处理、相控阵天线、时域分解光谱仪和全光计算等领域也有着潜在应用。
