Experimental research on specially optical bistability based on atomic ensemble

Abstract

Abstract Optical bistability (OB) phenomenon based on electromagnetic induced transparency has received widespread attention from researchers due to its good application prospects in ultrafast all-optical switches, high-speed all-optical exchange devices, optical storage, etc. In this paper, OB is realized in a thermal atomic ensemble by a probe transmission signal and a six-wave mixing signal. By adjusting the controllable parameters of the light field, such as the light field intensity, polarization state, incident angle of the light etc, the OB laws of related signal are discovered, analyzed, and summarized. These results will have potential application value in OB devices and signal processing.
