  • By applying a traveling-wave coupling field, a standing-wave grating field, and a static magnetic field to a cold atomic ensemble, a dynamically controlled cavity consisting of two Bragg regions of high reflection and an electromagnetically induced transparency region with high transmission is realized. With modulating all the three fields in time, a weak probe pulse is sent into the coherently induced optical cavity to achieve several periodic oscillations and then it is retrieved after a short time. This physical phenomenon is accompanied with little energy loss and can be regarded as an efficient scheme for dynamic light storage. This paper simulates the dynamic light storage scheme, discusses numerically its advantages and presents the developing trend of the scheme.
