Vacuum hollow-core optical fibres

博士项目将研究理论和数值模拟，以帮助真空空心光纤的发展，包括其设计和优化以及适当的表征技术。这将主要包括利用光纤中线性和非线性激光脉冲传播的光学方法，其中空心芯表现出不均匀且（在疏散期间）随时间变化的空气压力。此外，还将考虑这种真空光纤的应用，例如用于激光功率传输、最小噪声干涉仪和极端波长的传输，其中空气表现出强烈的损耗。

The PhD project will investigate theory and numerical simulations to aid the development of evacuated hollow-core optical fibres, including their design and optimisation and appropriate characterisation techniques. This will mainly include optical methods exploiting linear and nonlinear laser pulse propagation in such fibres where the hollow core exhibits a non-uniform and (during evacuation) time-dependent air pressure. Moreover, applications of such evacuated fibres will be considered, e.g. for laser power delivery, minimum-noise interferometers, and transmission at extreme wavelengths where air exhibits strong losses.
