Project description
Quasiparticles that could herald a breakthrough in photonic technologies
Exciton-polaritons are photonic-electronic quasiparticles arising from the strong coupling of light with matter in the form of an exciton. Angle-resolved measurements of light dispersion inside structures can reveal information regarding the strength of the light-matter coupling, but their application potential has largely been neglected. Funded by the Marie Skłodowska-Curie Actions programme, the PolDev project plans to develop organic polariton devices that leverage exciton-like dispersion in strongly coupled microcavities. Researchers will create interference filters with ultra-low angular dispersion, thereby offering a new route to designing optical systems. In addition, they will use these filters to design high-quality microcavity polariton light-emitting diodes with unprecedented colour purity for display applications.
Objective
The coherent coupling of photons and material resonances, known as strong light-matter coupling, has recently emerged as a concept to realise a variety of novel devices. By hybridising light in a micro- or nano-scale cavity with a material resonance, often an exciton to create exciton-polaritons, properties of both light and matter can be manipulated. While this has shown great promise in systems that exploit a change in energy levels of a material, such as in polariton chemistry, the resulting change of light dispersion has been largely neglected for applications. Within the project PolDev, I aim to realise organic polaritonic devices that make full use of the exciton-like dispersion in ultra-strongly coupled microcavities with suitable detuning. In doing so, I will realise interference-based transmission filters with ultra-low angular dispersion that will enable a new way of designing optical systems. I will further exploit this concept to design high-Q microcavity polariton light emitting diodes for display applications with unprecedented colour purity and to showcase new pathways for electrically pumped polariton lasing. The resulting devices will further be ported onto mechanically flexible platforms, paving the way for novel polaritonic applications.
