Tunnelling based birefringent rotary photon dragging through induced chiral medium

Abstract

The control and modification of divergence angle and birefringent rotary photon drags under the effect of quantum tunnelling is investigated in this article. The circularly birefringence , divergence angle θ d and rotary photon dragging angles are found to have modified with the strength of tunnelling frequencies. The left and right circularly polarized beams show superlominality of group velocities −c/150 and −c/50, respectively, and the divergence angle of 0.050 radian per increment of tunnelling frequency. The maximum of rotary photon drags for both beams is measured micro radian with fractional change of 2%. The output pulses intensities and show uniform undistorted shapes with tunnelling frequencies and no energy losses. The results could have significant applications in the fields of quantum optics, photonics, plasmonics and special mode imaging coding technology.
