Birefringence of rotary photon drags through induced chiral atomic medium

Abstract

The birefringence of rotary photon drags is investigated through induced chiral atomic medium. The birefringence of refractive and group indices, divergent angle and rotary photon drags were controlled and modified with detuning, phases and strength of Rabi frequencies of the driving fields. The value of divergent angle oscillated between ±0.01 radian with phases of control fields φ3,4 and is minimum at φ3 = π, while maximum at φ4 = π. The right and left circularly polarized beams are drag clockwise due clockwise spinning of the medium in the normal dispersive region, while the right and left circularly polarized beams are drag clockwise due anticlockwise spinning of the medium in anomalous dispersive region. The maximum rotary photon drags of birefringent beams of light is calculated to ±5 milli radian. The results show advancement in molecular structure, dual image coding and image designing technology.
