Nonlinear optical effects with low-power non-laser light

该项目旨在允许使用低成本、低强度的光源，如发光二极管和放电灯，在光子设备中产生非线性光学信号。非线性光学效应对电信和信号处理技术至关重要，目前只有在高功率激光产生光的情况下才可能实现。该项目的预期结果是一个理论和实验框架，将为开发一种不需要激光的新的非线性光子技术奠定基础，代表着光子设备设计方式的范式转变。这将通过国家宽带网络等媒体更便宜、更有效地传输信息，从而使侦测、电信和国防受益。

This project aims to allow the use of low-cost, low-intensity light sources, such as light-emitting diodes and discharge lamps, to generate nonlinear optical signals in photonic devices. Nonlinear optical effects are vital for telecommunication and signal processing technologies and are presently possible only when the light is produced by a high-power laser. The expected outcome of this project is a theoretical and experimental framework that would underpin the development of a new nonlinear photonic technology that does not require lasers, representing a paradigm shift in how photonic devices are designed. This should benefit sensing, telecommunications and defence by cheaper and more efficient transmission of information via media such as the National Broadband Network.
