Abstract

We demonstrate induced nonlinear optical processes, namely second- and fourth-harmonic generation, in an inversion-symmetric semiconductor quantum ring of GaAs by strongly coupling the system to a photon mode of a high-Q optical cavity. By treating the pump field as a quantized coherent state and solving the time-dependent Schrödinger equation for the coupled light-matter Hamiltonian, the work shows that strong light-matter coupling can break inversion symmetry, enable even-order harmonic generation, and increase conversion efficiency in a controllable way, especially in the few-photon limit.
