Coherent manipulation of birefringent superluminal bright solitons in a chiral medium

The superluminal solitonic propagation behavior of left- and right-circularly polarized (LCP/RCP) light beams is investigated in a chiral medium. RCP and LCP beam absorption exhibits super-Gaussian-type peak behavior with spatial coordinate fluctuation around the origin. The RCP beam’s subluminal phase velocity is v p ( + ) = c / n r ( + ) , and its refractive index is 5.47. On the other hand, the LCP beam’s superluminal phase velocity is v p ( − ) = c / n r ( − ) , and its refractive index is −3.65. Both LCP and RCP beams propagate at superluminal group speeds in the medium. The RCP and LCP beams’ maximum group index values are determined to be N g ( + ) = − 33522 and N g ( − ) = − 1305 . The group velocities that correspond to this are v g ( + ) = − c / 33522 and v g ( − ) = − c / 1305 . With the position of greater nonlinearity and periodicity changing with forward time flowing, the RCP and LCP pulses E ( r , t ) (+) and E ( r , t ) (−) exhibit superluminal-peaked soliton characteristics. With increasing forward time, the LCP pulse intensity shifts to a positive position while the RCP pulse intensity shifts to a negative position. The bright superluminal solitonic intensities
