About the Project

Our ambition is to explore light-matter interactions at the quantum level in nanocavities combining the confinement of light usually only achievable in plasmonic structures with the low losses found in dielectric photonic crystal cavities. This project aims at extending our fundamental understanding of the interaction between electromagnetic fields and excitons in a yet unexplored class of nanocavities. This explorative experimental work will lay the ground for future applications ranging from low-noise nanolasers [2] to polaritonic lasers [3] and single-photon blockade devices working at room temperature [4].The project is part of NanoPhoton and will take place at DTU Fotonik, who has expertise in the design, fabrication, and characterization of dielectric nanocavities, and the project will benefit from synergies with the Centre for Nanostructured Graphene (CNG) that has internationally recognized experience in the preparation and nanofabrication of 2D materials.The projectExtremely confined electromagnetic fields in topologically-optimized dielectric cavities offer a new platform to explore light-matter interactions in regimes of cavity parameters where the field confinement is similar to that of plasmonic systems, yet with large quality factors not achievable by metallic structures [1]. Combined with 2D materials showing excellent optical properties at room temperature [5], we will be able to explore a new range of light-matter coupling parameters not achievable otherwise.In this project, you will learn the basic principles behind strong light-matter interactions, dielectric nanocavities, and the excitonic properties of low-dimensional materials, working with samples that are fabricated within NanoPhoton at DTU Fotonik [6]. Your primary task will be to investigate the coupling dynamics between excitons in the 2D materials and photons in the cavities by use of ultra-fast spectroscopy. You will also have the opportunity to be trained and use near-field scanning optical microscopy to probe optical properties of the fabricated structures with a spatial resolution better than 20 nanometers [6]. You will analyse the experimental data and compare them with theoretical models in order to get a deeper understanding of light-matter interaction in these new structures. Based on your results, you will assess the possibility of designing novel platforms for low-noise lasers [2], polaritonic lasers [3], or single-photon blockade devices [4] for future applications in quantum technologies.
