Abstract:
The exciton polaritons in the semiconductor microcavity driven by light is a hot research field in physics and optics in recent years, and the superposition quantized vortex of the Bose-Einstein Condensates (BEC) driven by light in the microcavity has subversive potential application value in the field of quantum sensing. An accurate mathematical model via Runge-Kutta Difference and FDTD finite element method was constructed to characterize the time-space evolution of the quantum vortex gyrotron polariton system. On this basis, the influence of some key parameters related to pump light, signal light and semiconductor microcavity materials on the evolution characteristics of the quantum vortex gyroscope exciton polariton condensate was studied. For the pump light and signal light, the light intensity and geometric size of the annular spot were considered. Meanwhile, the effect of the microcavity material on the exciton polariton system was converted into the effect of the effective mass on the BEC system through mathematical transformation. By scanning a lot of parameters, some key factors affecting the performance of the quantum vortex gyroscope were obtained, including the geometric parameters and intensity of the pump light, the related influence of the pump light and the signal light, and the material properties of the semiconductor microcavity. The relationship between material properties and superposition state evolution of quantum vortex gyroscope was calculated by characterizing the relationship between effective mass and properties of different microcavity materials, and the range of reasonable values for effective mass was found to be narrow. These works provided an important reference for the engineering prototype development of the quantum vortex gyroscope.
