| Abstract: | Based on the strong coherent interaction between a three-level ladder-type atom and a fiber-taper-coupled microtoroidal resonator, we present a scheme for optical transmission gratings. Using experimentally accessible parameters, it is shown that alternating regions of high transmission and absorption can be created in the fiber-taper channel by spatially modulating an external coupling field. The model shows an obvious effect which has a direct analogy with the phenomenon of electromagnetically induced grating (EIG) in quantum systems. |
