- Abstract
In this article we have theoretically investigated the rotary photon drag without and in the presence of single and dual cross-Kerr nonlinearity in a four-level atomic medium. The dynamics of the atomic medium are derived using the density matrix method. We have investigated that the single Kerr nonlinear effect gradually enhanced the rotary photon drag, while dual Kerr nonlinear effects largely enhanced the rotary photon drags ( ± 1000 μ rad ) for significant technological application. Furthermore, we have studied larger group index under the effect of single and dual cross Kerr nonlinearity ( n gkk > > n gk > n g ). Likewise, we have also investigated delay time without and with single and dual cross-Kerr nonlinearity. We have observed 2 μ s delay time without the Kerr effect, while 3.2 μ s and 50 µs delay time in the presence of single and dual cross Kerr nonlinearity. These results may have potential useful applications in the fields of quantum optics, photonics, imaging designing and special modes of imaging coding technology.
