Photonic coherent perfect transmission, absorption, and synthesis in a bimodal cavity quantum electrodynamics system

Abstract

In this paper, we investigate an optical hybrid system in which a single quantum emitter is coupled to both modes of a bimodal optical microcavity, and propose a scheme for coherent perfect transmission, coherent perfect absorption, and coherent perfect synthesis of optical photons by utilizing such a bimodal cavity quantum electrodynamics (QED) system. In the present scheme, each mode of the bimodal microcavity can be coherently driven by an external monochromatic continuous-wave driving laser and the two cavity modes are not directly coupled to each other due to their orthogonal polarizations. It is found that three important phenomena, i.e., photonic coherent perfect transmission, absorption, and synthesis can be achieved in the optical hybrid system under appropriate conditions. We discuss in detail the theoretical model and present results of numerical simulation of the system in the steady state with experimentally achievable system parameters. Also, the possible experimental realization of the scheme in a solid-state approach is analyzed based on the semiconductor quantum dot and the photonic crystal defect microcavity. This study may provide further insight into the understanding of bimodal cavity QED system and find potential applications in quantum information processing and future quantum networks.
