Summary of Interests

My scientific interest is focused on light-matter interaction in the classical and quantum regime in Condensed Matter Physics. It relies on three milestones: a light emitter (electronic system, generally such as quantum dots, quantum well, nanocrystals,...), a photon mode (or many!) and a coupling between them. Reducing the size of these electro-optic systems allow to reach high scalability. Moreover, from a Physical point of view, it allows to reach original Quantum Physics allowing fruitful light-matter manipulation. In addition to this rich Physics (ex: Cavity Quantum ElectroDynamics or polariton Bose-Einstein condensation), these systems provide new tools with impressive figure of merit in nanotechnologies and in the related fields such as biological and chemical sensing (ex: optical detection of a single protein).

Sensing, characterisation and manipulation at the nanoscale using optical microcavities
Prof Jason Smith and Dr Aurelien Trichet

Optical sensing and spectroscopy are powerful tools for detecting and characterising nanoparticles at the single particle level. Pollutants and aerosols or microbiological organisms such as viruses have characteristic optical signatures based on their refractive index, size, and polarisability as well as spectral signatures that allow them to be identified and studied. This project will develop novel optical microcavities as means of confining light such that its interaction with nanoparticles is both strengthened and highly controlled. These microcavities show great potential for the trapping and manipulation of particles, and for particle identification using refractive index and spectroscopic methods. The project will involve fabrication of cavity devices and using them to perform some foundational experiments in this area. The student project is part of a larger effort within the group, in collaboration with Dr Claire Vallance in the Department of Chemistry.
