Quantum Fluctuation Power Spectrum of Light Field in the Dielectric Interface System of Plasma / Dispersion Absorption Cavity

Abstract

In recent years, people have shown great interest in the quantum theory of light field in one-dimensional optical cavity composed of dispersive absorbing medium. However, up to now, only the vacuum in the cavity has been studied for one-dimensional dispersive absorbing medium symmetric cavity system in the existing literature, and there is no report of cavity loading. In this paper, the effect of plasma loading on the quantum properties of a dispersive absorbing dielectric cavity system is studied. The results show that the spatial distribution of the fluctuation power spectrum of the vacuum field in the system is significantly changed by the dielectric loading. The working state of the plasma loaded cavity is closely related to the selected optical field frequency. The results are valuable for the study of the quantum fluctuation power spectrum of the optical field in the dielectric interface system of plasma / dispersion absorption cavity.
