“…In the following section, we will focus on the influence of the E 2 field at different angles on the OB of the PTS and SWM signals. Since the change in the E 2 field angle will cause a change in the signal phase difference, the first-order and fifthorder density matrix of the system should introduce a phase factor ∆φ [16]. The specific expression is as follows: Finally, we will fix the E 2 field intensity to 30 mW, which produces an obvious spectral intensity asymmetry, adjusting the incident angle of the E 2 to 0.3 • to generate EIA dips for PTS and add a QWP in front of the E 2 field to observe the OB of the PTS and SWM signals as the QWP changes.…”

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.

We illustrate the experimental observations of Autler-Townes splitting and the spatial splitting in an electromagnetically induced transparency window in a atomic vapor system of D1 line. As the power of the dressing laser beam changes, we study first-order and secondary Autler-Townes splitting. The influences of these dressing beams, which lead to the larger spatial splitting of four-wave mixing and the shift of probe transmission signal with by changing frequency detuning. Studies on such controllable Autler-Townes splitting and spatial splitting effect can be very useful in applications of spatial signal processing and optical communication.
