Topological charge transfer in microwave-driven quantum systems

Abstract

In this study, a four-level microwave-driven system is proposed for the transfer of the topological charge from an optical vortex light to a freshly created signal light. By adjusting the microwave field’s intensity, we first investigated the exchange efficiency of the created light. We talked about the exchange efficiency versus the propagation distance and the probe detuning, respectively. We came to the conclusion that the microwave light’s strong value makes it possible to achieve significant exchange efficiencies. Next, we talked about how the created light’s absorption and dispersion spectra varied depending on azimuth. We discovered that altering the azimuthal angle of the vortex light allows the absorption curve to be transformed into the gain spectrum. Additionally, we demonstrated how altering the azimuthal angle might alter the dispersion’s slope. Topological charge of the vortex light has also been used to explain the spatially dependent absorption spectrum of the generated light. We’ve discussed the spatial dependence of the intensity and phase distributions of the created light in the conclusion. We have established that the topological charge can be exchanged very effectively from optical vortex light to newly produced light.
