0401269ToulouseAll-optical functions are expected to become increasingly important in future communication networks. Recent developments in optical fibers, specifically the development of highly nonlinear silica fibers using a small size core as well as the new microstructured fibers (MF), have made the nonlinear optical fiber a top candidate for the realistic implementation of the above mentioned all-optical functionalities. In this project the PI will study several nonlinear optical effects in microstructured fibers and demonstrate their application to the functionalities required by an All-Optical Network. The originality and scientific merit of the proposal is that it combines a study of basic optical phenomena in microstructured fibers with the demonstration of network functionalities. Several types of microstructured fibers are being developed and studied, each geometry being designed to enhance a certain nonlinear optical property. In particular, the PI will focus on stimulated Raman scattering, which offers several advantages for applications in an all-optical network, such as wavelength conversion, ultrafast optical sampling and possibly also data regeneration. The proposed research will have several broader impacts. The first one is the expansion of the knowledge base that underlies existing optical technologies. A second one is the application of technologies that, so far, were primarily used in optical communications, to other areas such as sensing, bio or medical applications. The new Lehigh Center for Optical Technologies will also greatly help with the dissemination of information and knowledge generated by the project and facilitate cross-fertilization.

0401269图卢兹全光功能在未来的通信网络中将变得越来越重要。光纤的最新发展，特别是使用小尺寸芯的高度非线性石英光纤以及新的微结构光纤（MF）的发展，已经使非线性光纤成为上述全光学功能的现实实现的最佳候选者。在这个项目中，PI将研究微结构光纤中的几种非线性光学效应，并展示它们在全光网络所需功能中的应用。该提案的独创性和科学价值在于，它将微结构光纤中基本光学现象的研究与网络功能的演示相结合。正在开发和研究几种类型的微结构光纤，每种几何形状都被设计成增强某种非线性光学特性。特别是，PI将集中在受激拉曼散射，它提供了在全光网络中的应用，如波长转换，超快光学采样，也可能数据再生的几个优点。拟议的研究将产生几个更广泛的影响。 第一个是扩大现有光学技术的知识基础。 第二个是将迄今为止主要用于光通信的技术应用于传感、生物或医疗应用等其他领域。 新的利哈伊光学技术中心也将大大有助于传播该项目产生的信息和知识，并促进相互交流。
