Optical bistability and multistability via multi-Raman-channel interference
Abstract
We investigate the optical bistability and multistability behaviors in a closed three-level \Lambda-type atomic system. By adding a sideband on either hand of the transitions which are originally coupled by a coherent control field and a coherent probe field to disturb the two-photon resonance, bistability occurs due to two-channel interference. Increasing the sideband Rabi frequency leads to the switching from bistability to tristability. When the sideband simultaneously couples with both hands, we can easily obtain quadrastability.
