Low intensity nonlinear optics in the THz regime

该项目将探索液晶和有机薄膜及其在太赫兹光束操纵中的应用，探索它们与人工微结构和纳米结构表面(超表面)的强烈相互作用。超表面将在洁净室中设计和制造，然后通过实验表征，以测量电场的局部增强和与空间相关的材料参数。该项目还包括建立模型来研究强光-物质相互作用的基本物理。多学科博士研究提供了基础科学和应用科学的良好平衡，将两者结合起来，以推动我们团队在太赫兹光子学和液晶器件方面的成功研究。

The project will explore liquid crystals and organic thin films and their use for THz beam manipulation, exploring their strong interaction with artificially micro- and nano-structured surfaces (metasurfaces). The metasurfaces will be designed, fabricated in the cleanroom and then characterised experimentally to measure the localised enhancement of the electric field and the spatially dependant material parameters. This project also involves modelling to study the underlying physics of strong light-matter interaction. Theis multidisciplinary PhD research offers a good balance of fundamental and applied science, uniting the two in order to take forward our groups' successful research in THz photonics and liquid crystal devices.
