Abstract

New scheme of a real-time all-optical switching (AOS) was demonstrated as the fluorescence signal of cesium twophoton transition (TPT) with the control field. This work explored the optical phenomenon of the TPT with the control field that shares a common excited state, in which the TPT fluorescence is quenched under the control field intensity. The strong stimulated emission due to the control laser suppresses the TPT fluorescence, working as an optical switch. A "NOT gate" is generated for realization of AOS. The power spectrum of the intensity range, which can be used for the AOS, is determined.
