The 'ACCESS' Project: Network Access in Optical Communications Systems.

剑桥大学工程系的研究人员利用硅基液晶（LCoS）技术开发了实时纯相位全息技术。这似乎是可用的最通用的光交换方法。它使可扩展的低损耗多播、波前控制甚至可编程的噪声场控制成为可能。由于它将许多功能结合到一个灵活的可编程模块中，并支持实时配置和网络管理，因此全息LCoS模块比竞争技术具有显着优势。随着电讯网络对带宽的需求增加，光纤将被部署在更靠近客户的地方，这将要求每个社区或建筑群都有这样的光互连，为该模块提供了巨大的潜在市场。申请人先前的工作导致了首个设计用于电信c波段操作的lco设备。本提案旨在开发LCoS研究设备，并将该技术纳入功能演示器。

Researchers in the Engineering Department of Cambridge University have developed techniques for real-time phase-only holography utilising Liquid Crystal over Silicon (LCoS) technology. This appears to be the most versatile method of optical switching available. It makes possible scalable low-loss multicasting, wavefront control and even programmable control of noise fields. Because it combines a number of functions into a single flexible, programmable module and enables real-time configuration and network management, the holographic LCoS module has significant advantages over competing technologies. As the bandwidth requirements of telecommunications networks increase, optical fibres will be deployed nearer to the customer which will require each neighbourhood or building complex to have such an optical interconnect, providing a large potential market for the module.Previous work by the applicants led to the first LCoS device designed for operation in the telecommunications c-band. This proposal is intended to develop the LCoS research devices and incorporate the technology into a functional demonstrator.
