摘要

In this research, we presented a four-level atomic model to investigate the impact of rotary photon drag on temporal cloaking, taking into account the influence of Kerr nonlinearity with stepwise increases in Kerr field intensity. The temporal cloaking intervals we recorded were \(5 \mu s, 9.6 \mu s, 15.6 \mu s, 22.8 \mu s,\) 5 μ s , 9.6 μ s , 15.6 μ s , 22.8 μ s , and \(31.4 \mu s\) 31.4 μ s . Additionally, our findings indicate that while the temporal gap remains consistent during the light beam's transmission along the mechanical axis of rotation under the effect of rotary photon drag, the pulse intensity experiences distortion with increasing dragging angle. The numerical outcomes suggest promising applications in fields such as image design, image encoding, photonic crystal discovery, optical sensing technology, and secure communication with reduced noise between transmission and reception channels.
