Strong light-matter coupling based optical computing

Optical computing devices and neural networks are inherently capable of tackling pattern recognition tasks and handling big data, which are essential for artificial intelligence. Nonetheless, using photons to achieve efficient computation continues to be a significant challenge. Photon-photon interactions are considerably weaker and necessitate high intensities, significantly restricting their applicability in optical computing components such as switches and transistors.

Light can strongly couple with organic semiconductor molecules and materials at room temperature, forming exciton-polaritons that are quasiparticles with both light and matter properties. Polaritons can substantially modify excited energy states and display nonlinear optical characteristics. Interparticle interactions in exciton-polaritons can be orders of magnitude greater than weakly interacting photons, making them exceptional candidates for optical computations. In this project, you will experimentally investigate and utilise exciton-polaritons for efficient optical computations. The project provides opportunities to concentrate on devices or spectroscopy in collaboration with theorists, experimentalists, and our industry partners.

The successful candidate will conduct experimental work in Prof. Girish Lakhwani's research group in the School of Chemistry. For further information, please visit the group website or contact Prof. Lakhwani.

If you're interested in applying for this project, email Prof. Lakhwani with your CV, academic transcripts, and a cover letter that clearly outlines how your research experience aligns with the project objectives. Incomplete applications will not be processed.
