Tunnelling Based Birefringent Rotary Photon Dragging Through Induced Chiral Medium

The control and modification of divergence angle and birefringent rotary photon drags under the effect of quantumtunnelling is investigated inthis article. The circularly birefringence Delta n = n(r)((+)) - n(r)((-)), divergence angle theta(d) and rotary photon dragging angles theta((+/-))(r) are found to have modified with the strength of tunnelling frequencies. The left and right circularly polarized beams showsuperlominality of group velocities -c/150 and-c/50, respectively, and the divergence angle of 0.050 radian per increment of tunnelling frequency. Themaximumof rotary photondrags for both beams is measured theta((+/-))(r) = +/-2 micro radianwith fractional change of 2%. The output pulses intensities E-out(+)(t)vertical bar(2) and E-out(-)(t)vertical bar(2) showuniformundistorted shapes with tunnelling frequencies and no energy losses. The results could have significant applications in the fields of quantum optics, photonics, plasmonics and specialmodeimaging coding technology.
