Modeling the optical response of monolayer molybenum disulfide in a cavity
Abstract/Contents
- Abstract
- As semiconductor-based systems face heat dissipation and signal distribution issues, the focus has shifted to on-chip nano-photonics as a promising replacement. Unlike the traditional architectures, photonic resonators such as optical cavities are controlled by electromagnetic radiation instead of electrical voltage. The key challenge lies in generating a nonlinear input-output relationship. To this end, one popular solution is to couple the resonator to a saturable absorber. Here, we will focus on the prospect of using monolayer molybdenum disulfide (MoS2) as the saturable absorber, with the material placed inside a Fabry-Perot cavity at low temperature. The strength of the interaction between the excitons of monolayer MoS2 and the electromagnetic field is calculated by deriving the electronic band structure of the material and superposing transition amplitudes between valence and conduction band states. Unlike a multi-atom cavity, the interaction between different excitons has a significant effect on the input-output relationship of the cavity. We will show the theoretical model required to calculate the exciton-photon coupling coefficient and the exciton-exciton annihilation rate, eventually culminating in the use of a Lindblad-Hamiltonian formalism to derive the optical nonlinearity for the cavity-material system.
