Space-time cloaking through a chiral atomic medium

Abstract

The birefringence characteristics of reflection and transmission of light pulse are explored in chiral medium driving by two probe electric and magnetic fields, while four control fields. The proposed medium show significant birefringence behaviors in reflection/transmission and Goos-Hänchen (GH) shifted beams. The birefringent GH-reflected and GH-transmitted pulses show significant contribution in the space time gap creation for secure communication and invisibility. A space-time gap has been observed in the reflection, transmission and corresponding GH-shifted reflection and transmission birefringent beams. The theoretical results may be useful for noise free secure communication in invisible radar technology.

The impact of cross-Kerr nonlinearity on rotary photon drag and temporal cloaking in Sagnac interferometry

“…Lee et al [40] have also demonstrated optical cloaking and invisibility. Ahmad et al [41] proposed a novel scheme to investigate space-time cloaking in a chiral atomic medium. Additionally, they achieved significant birefringent behaviors for the Goos-Hänchen shifted beams.…”
