Abstract

Atomically thin van der Waals (vdW) materials have generated strong interest in the community due to its unusual physical properties and possibility of creating high-performance devices. However, the ultrathin nature of these materials limits the achievable light-matter interaction. One promising way to increase such interaction is via nanophotonic confinement of light. In fact, researchers have demonstrated various nanophotonic devices using such vdW materials, including optically pumped lasing, second harmonic generation, cavity enhanced electroluminescence, and exciton-polaritons. In this talk, I will explore the possibility of going to quantum optical regime using this material system integrated with nanophotonic resonators. I will discuss the role of exciton-phonon interaction in the cavity photoluminescence spectrum and present a quantum optical model of the coupled system in presence of the phonons. I will then report the observation of the exciton-polaritons using TMDs.
