Manipulation and Shaping of Light in the Far-Field using Advanced Fresnel Fibres

点击翻译按钮获取中文摘要

This project will focus on developing and understanding further the recent invention of the Fresnel fibre, which is designed to overcome diffraction from the end of an optical fibre. More sophisticated designs and combinations will allow arbitrary shaping of the optical field exiting an optical fibre for numerous applications. The physical basis for such phenomena to be realised is the efficient degree of coherent scattering possible in air-material fibre such as air-silica photonic crystal fibres. In conjunction advanced characterisation techniques will be developed.
