Mid-infrared absorption spectroscopy is the most widely used technique for detecting the molecular signatures of an unknown sample using their fingerprint absorption. Waveguide evanescent field based spectroscopy can detect analytes at very low concentrations using their absorption fingerprints, potentially offering high sensitivity and selectivity over a wide range of compounds without labelling.The ideal molecular "fingerprint" region for biochemical analysis is dominated by the Mid-IR spectral region from 2 micrometres - 13 micrometres. This project will explore novel Mid-IR waveguide based integrated photonic devices and will help realise photonic lab on-chip platform for biomedical diagnostic applications. Specifically this will involve the fabrication and characterisation of waveguides (using novel Mid-IR materials) and waveguide based devices such as ring resonators, on-chip sources and Mach-Zehnder interferometer, and their integration. The project will also involve electromagnetic modelling of some of these devices for optimising the performance and for designing photonic circuit layouts.

中红外吸收光谱是使用指纹吸收检测未知样品分子特征的最广泛使用的技术。基于波导倏逝场的光谱学可以利用其吸收指纹检测非常低浓度的分析物，潜在地在广泛的化合物上提供高灵敏度和选择性而无需标记。生化分析的理想分子“指纹”区域由2微米至13微米的中红外光谱区域主导。该项目将探索基于新型中红外波导的集成光子器件，并将有助于实现用于生物医学诊断应用的光子实验室芯片平台。具体而言，这将涉及波导（使用新型中红外材料）和基于波导的设备，如环形谐振器，片上源和马赫-曾德尔干涉仪的制造和表征，以及它们的集成。该项目还将涉及其中一些设备的电磁建模，以优化性能和设计光子电路布局。
