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

剑桥大学工程系的研究人员已经开发出利用硅上液晶（LCoS）技术的实时纯相位全息技术。这似乎是最通用的光开关可用的方法。它使得可扩展的低损耗多播、波前控制甚至噪声场的可编程控制成为可能。全息LCoS模块将多项功能整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，因此与竞争技术相比具有显著优势。随着电信网络的带宽需求的增加，光纤将被部署得更靠近客户，这将要求每个社区或建筑群具有这样的光学互连，为模块提供了巨大的潜在市场。申请人的先前工作导致了第一个被设计用于在电信c波段中操作的LCoS设备。该提案旨在开发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.
