Description
Summary:. We propose a scheme for intracavity electromagnetically induced transparency and white light cavity via three-level Ladder-type Rb atoms. The system is driven by coherent and incoherent fields. Due to the position dependent atom-field interaction, the tunable optical susceptibility of the probe field can be achieved. By using an incoherent pump field and choosing proper parameters, one can control dispersion behavior of the probe field. In weak probe field limit, cavity bandwidth narrowing and broadening could be controlled via atomic systems in different conditions. Assuming the intracavity electromagnetic-induced transparency and the white light cavity conditions, it’s possible to control the susceptibility to satisfy the resonance condition over a wide frequency range. Tuning and controlling bandwidth of the optical cavity may find interesting applications in investigating cavity-QED phenomena and designing novel all-optical devices such as optical switches.
