This proposal is for Platform funding to provide career continuity for highly experienced research staff working in support of four key strands of the Photonics Research Group's strategy.Laser processing using fs pulses: the recent development of laser sources emitting very shot pulses with high peak power has created a wealth of material processing possibilities. The focussed laser beams can be used to create controllable modifications to the properties of any transparent material with a resolution of less than a micron and this enables the direct inscription of waveguides and other more complicated structures. Higher powers can be used to remove material from the substrate, allowing the machining of micron sized features. We plan to enhance and combine our expertise in micro-machining and laser modification to create a range of novel micro-miniaturised devices with unique properties, for applications in optical sensing and communications.Advanced grating sensors: fibre Bragg grating and long period grating sensors are periodic structures recorded in the core of a single mode silica fibre, usually with ultraviolet light. They diffract light of a well defined wavelength, which is influenced by the device's environment, and have been finding increasing application in optical communications and sensing systems. We plan to significantly enhance the capability of these kinds of devices by combining our ability to produce them using the more flexible fs laser inscription approach with novel fibre geometries and/or the use of other materials, e.g. polymers, which possess radically different physical properties to the silica used for conventional fibres.Systems and component modelling: theoretical and computational modelling will be carried out in three main areas in support of our experimental work. (i) We will undertake extensive direct statistical modelling of advanced modulation formats performance and error statistics in high-speed, spectrally efficient WDM transmission; (ii) we will design advanced photonic components for telecom and non-telecom applications, and (iii) we will develop models of high-power fibre lasers for fs inscription applications.Optical communications: much of our effort here is related to dispersion / the dependence of the velocity of light on its wavelength. Dispersion in optical fibres leads to a serious problem for today's ultra-high bandwidth systems, causing the very short pulses required to broaden as they travel down the fibre, eventually overlapping with their neighbours and rendering it impossible to recover the original data stream. Advanced techniques will be studied for mitigating the effects of dispersion in long haul transmission systems and entirely novel applications of a dispersive interferometric device / the Gires-Tournois etalon / will be sought in a range of fields. In addition, work will be carried out developing technology underpinning the realization of the all-optical communications network.

本提案旨在为平台提供资金，以便为支持光子学研究小组战略的四个关键方面的经验丰富的研究人员提供职业连续性。使用飞秒脉冲的激光加工：最近开发的发射具有高峰功率的非常短脉冲的激光源创造了丰富的材料加工可能性。聚焦激光束可用于对任何透明材料的特性进行可控修改，分辨率小于1微米，这使得波导和其他更复杂结构的直接雕刻成为可能。可以使用更高的功率来从衬底去除材料，从而允许加工微米尺寸的特征。我们计划加强和联合收割机我们在微加工和激光改性方面的专业知识，以创造一系列具有独特性能的新型微机械化器件，用于光学传感和通信。先进的光栅传感器：光纤布拉格光栅和长周期光栅传感器是记录在单模石英光纤芯中的周期性结构，通常用紫外光。它们吸收受设备环境影响的明确波长的光，并且在光通信和传感系统中的应用越来越多。我们计划通过将我们使用更灵活的飞秒激光刻写方法生产这些器件的能力与新型光纤几何形状和/或使用其他材料（例如聚合物）相结合，来显著提高这些器件的能力，这些材料具有与传统光纤所用二氧化硅完全不同的物理特性。系统和组件建模：为支持我们的实验工作，将在三个主要领域进行理论和计算模拟。(i)我们将对高速、高频谱效率WDM传输中的高级调制格式性能和误差统计进行广泛的直接统计建模;（ii）我们将为电信和非电信应用设计高级光子器件;（iii）我们将开发用于飞秒写入应用的高功率光纤激光器模型。光通信：我们在这里的大部分努力都与色散/光速对波长的依赖性有关。光纤中的色散导致了当今超高带宽系统的严重问题，导致非常短的脉冲在沿光纤传播时需要加宽，最终与相邻的脉冲重叠，从而无法恢复原始数据流。将研究先进的技术，以减轻长距离传输系统中的色散效应，并将在一系列领域中寻求色散干涉仪/Gires-Tournois标准具/的全新应用。此外，还将开展工作，开发支持实现全光通信网络的技术。
