Swapping of optical vorticity in a three-level coherent media

Abstract

In this paper, we have spoken about how the superposition of two upper states and the quantum interference effect affect exchange efficiency in a V-type atomic system. We have demonstrated that the same orbital angular momentum can generate an additional signal field in response to a single optical vortex light acting on one transition of the V-type quantum system. We have also discussed about how the exchange efficiency of optical vorticity is affected by the quantum interference term, the probe’s detuning, and the superposition of the higher states. Our model is ideal for quantum information processing based on the orbital angular momentum of light due to the enhancement in exchange efficiency.
