Abstract Details

2020, Master of Science, Miami University, Physics.
Quantum states of light with a fixed number of photons are useful for several quantum optical technologies. In this thesis, we theoretically study single-photon generation in a three-mode optomechanical cavity with a Kerr type nonlinear medium. We begin by presenting a detailed derivation of the master equation under Born-Markov approximations describing the dissipative dynamics of our setup. Next, we concentrate on two system parameters, the three-mode coupling rate (g) and the strength of the Kerr nonlinearity (U) and analyze the detuning (Δ) dependence of the second-order correlation function g(2) to determine the photon statistics. As a key finding, we analytically conclude that the system can exhibit UPB for a wide range of detunings even with weak nonlinearities by adjusting the three-mode coupling. For instance, we find that the condition g(2) (0) < 1 can be met with fixing U== 0.69k and 푔 = 2k while κ here represents the optical mode decay rate. Moreover, we observe that the minimum of g(2) (0) shifts to higher detunings with increasing three-mode coupling rate and decreasing the Kerr nonlinear strength. With the current advancements in hybrid optomechanics, this work is experimentally feasible and can provide an alternate method for single-photon generation without relying on stringent conditions of CPB.
