Summary on Grant Application Form
Future fibre-optic technologies will rely on high-performance, versatile and fast systems. Although nonlinear optical materials offer a wealth of effects that perform different functions on light, their potential is not fully used in fibre telecommunications technology. This gap between nonlinear optics and technology needs to be addressed. I aim to concentrate on this issue in my proposed work.I propose to explore nonlinear light propagation in novel optical fibre structures, and its applications in optical technology. The underlying idea is to use microstructured fibres to deliver light efficiently to nonlinear media that are incorporated into their structures. I have identified two geometries whose potential for nonlinear optics can only now be explored following recent developments and refinement of their fabrication, namely photonic crystal fibres and tapered fibres. Nonlinear effects, such as controllable coupling between guides and switching, should be possible, as well as spatial solitons. Interfacing nonlinear materials with microstructured fibres should provide the basis for a new generation of nonlinear fibre devices, such as soliton-based nonlinear couplers, reconfigurable switches, wavelength convertors, and cross-connect devices capable of routing and frequency-shifting of signals.The broad programme of research I propose will provide further understanding of fundamental physical processes, as well as new device developments in these technologically important systems.
