Vibrational pumping of molecules in tightly-confined plasmonic nanocavities

该项目旨在研究脉冲中红外激光照射-泵浦分子振动跃迁-如何在随后耦合到等离子体纳米空间的分子的拉曼散射光谱中产生非线性特征。这些观测将用于探测分子表面相互作用，腔-分子系统的光学机械描述，并提供关于中红外辐射如何在等离子体腔中被吸收的洞察，这与实现新一代太赫兹探测器有关。

The project aims to study how pulsed mid-infrared laser irradiation --- pumping molecular vibrational transitions --- produces nonlinear signatures in subsequent Raman scattering spectra of molecules coupled to plasmonic nanocavities. These observations will be used to probe molecular surface interactions, the optomechanical description of cavity-molecule systems and provide insight into how mid-infrared radiation is absorbed in plasmonic cavities, relevant towards realising a new generation of THz detectors.
