Spherical manipulation of lateral shifts in reflection and transmission through chiral medium

Abstract

The spherical manipulation of subluminal and superluminal light propagation and corresponding GH shifts in reflection and transmission through a chiral medium is investigated in this manuscript. The subluminal and superluminal propagation of group velocity ±2×106m/s is investigated in the spherical direction for both left and right circularly polarized (LCP/RCP) light beams in a chiral medium. A Dumbbell shape GH shifts in reflection and transmission spectrum is reported for LCP and RCP beams in the spherical manipulation. Positive and negative GH shifts in reflection and transmission beams are reported for LCP and RCP beams. The maximum GH shifts in reflection beams of LCP and RCP are calculated to ±20?, and transmission beams are investigated to ±1? in all directions and have contrast behaviors of GH shifts of LCP and RCP beams. The RCP and LCP beam pulses in the reflection oscillated in the range of ±4 amplitudes in all directions, while the transmission oscillated in the range of ±5 and ±2 amplitudes in different directions. The modified results are useful for optical sensors. © 2024
