Single-Photon Level Electromagnetically Induced Transparency Based on Dipole Blockade Effect
The transmission properties of the quantized probe field traveling in one-dimensional ultra-cold Rydberg atom samples are studied. Based on the dipole blockade effect, the steady-state spectrum of the electromagnetically induced transparency (EIT) of a four-level atom exhibits the typical nonlinearity at single-photon level. Namely, the field transmittance and photon correlation depend on the probe field intensity before the saturation. By changing the single-photon detuning of the two classical control fields, we realize the flexible manipulation of the nonlinear EIT behavior. By varying the ratio of the Rabbi frequencies, we can observe the transformation of nonlinear EIT from the four-level atomic system to the three-level trapezoidal atomic system.
