Abstract :
New scheme of a real-time all-optical switching (AOS) was demonstrated as the fluorescence signal of cesium two-photon 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 quenched under the control field intensity. 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.
