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.Read moreRead less
Light-matter interactions in microstructured optical waveguides for nonlinear optical signal processing. The challenge of conceiving and constructing the necessary components and devices for the next generation of lightwave telecommunications systems is a profound one. This issue is urgent as the current operating principles of switches, filters and sources and other devices simply do not allow for the upgrade to the extremely high data transmission speeds that will be required. Using glass opti ....Light-matter interactions in microstructured optical waveguides for nonlinear optical signal processing. The challenge of conceiving and constructing the necessary components and devices for the next generation of lightwave telecommunications systems is a profound one. This issue is urgent as the current operating principles of switches, filters and sources and other devices simply do not allow for the upgrade to the extremely high data transmission speeds that will be required. Using glass optical fibres as the starting point, we will devise, demonstrate and analyze these novel components, leveraging microstructured optical fibre technology and novel fabrication techniques, which are among the most recent developments in optical fibre research.

Fine Structured Optical Fibre Fabrication - Soot, Rheology and Nanostructure in Modified Chemical Vapour Deposition. For 30 years photonics and telecommunications have relied heavily on optical fibres made by Modified Chemical Vapour Deposition (MCVD), a complex, highly dynamic process with many interacting variables, which is still more art than science. The results are good enough for most purposes but the next generation of photonics demands fibres with intricate, precisely defined internal s ....Fine Structured Optical Fibre Fabrication - Soot, Rheology and Nanostructure in Modified Chemical Vapour Deposition. For 30 years photonics and telecommunications have relied heavily on optical fibres made by Modified Chemical Vapour Deposition (MCVD), a complex, highly dynamic process with many interacting variables, which is still more art than science. The results are good enough for most purposes but the next generation of photonics demands fibres with intricate, precisely defined internal structures. A multi-disciplinary team will elucidate and quantify the exact nature of the fundamental science underlying MCVD - of silicate soot formation, deposition and heat treatment - and translate this into reproducibly fabricated fine structured fibres with high optical and mechanical performance.Read moreRead less

Recent developments involving holographically patterned photosensitivity in glass-based optical waveguides developed by our group can be extended to fabricate complex two-dimensional structures including planar waveguide photonic bandgap devices for applications in telecommunications, sensing and signal processing. These will include novel grating-array based 2-D DFB lasers and filters in rare-earth doped planar waveguides. Novel etching techniques to be used to enhance index contrast, as well as to characterise such devices, will be developed based on our recent observation of hydrogen-enhanced etching of glass. Such methods could potentially be applicable to not only photonic technologies but also semiconductor lithography of oxides.Read moreRead less

Mechanical stresses in holey fibres. The development of holey fibres constitutes arguably the most exciting development in fibre optics in recent years. We will analyze the mechanical stresses in these fibres, which, together with the optical calculations and associated experiments, will allow us to design novel fibre-based devices. This will allow Nufern to develop new products based on holey fibres.
