Quantum light-matter interaction of two-dimensional optical transitions coupled to dielectric microresonators

Abstract

Photonic integrated circuits have the potential to be a disruptive technology comparable to the success of electronic integrated circuits. The absence of a compact, low-power all-optical nonlinearity limits the capability for information processing and communication applications. Dielectric microresonators and the heterogeneous integration of optical transitions such as color centers, quantum dots, and quantum wells have distinct advantages for integrated nonlinear optics. This thesis explores the light-matter interaction of two-dimensional materials supporting an excitonic optical transition coupled to dielectric microresonators. A compact expression for calculating the light-matter interaction is presented. The theoretical estimate of the light-matter interaction and input-output characteristics of the exciton-resonator system agrees with experimental observations. Exciton-phonon interactions are incorporated into the Hamiltonian model to describe the asymmetric cavity-coupled photoluminescence observed in experiments.
