“…It is shown that growing of temperature leads to lower EIT depth and narrower EIT width. The physical reasons to explain this tendency are attributed to reduction of atomic coherence as growing thermal atomic motion, and growing of atomic density as heating the Rb cell over the melting point of Rb (about 312 Kelvin [76]).…”

“…Although the numerical simulations on the EIT spectrum in [71,72] were helpful to explain experimental observation, there is still a lack of analytical representation of EIT spectrum which is important for various applications. In order to overcome this lack, Bang and co-workers have recently developed an analytical method to represent the EIT spectrum [74][75][76]. Such analytical model supports several interesting works concerning giant Kerr nonlinearity [77], OB [78], generating optical nano-fiber (ONF) for guiding entangled beams [79], slowed multi-frequency light [80,81], and lossless propagation of light pulse [34,35].…”

The advent of electromagnetically induced transparency (EIT) offered a new coherent material with exotic and controllable optical properties. Although, studies on single-EIT are described in detail for single-EIT, however, extension from single- to multi- EIT is currently of current interest due to it gains advantages in multi-channel optical communication, waveguides for optical signal processing and multi-channel quantum information processing. In this work, we review recent research works concerning multi-EIT and some related applications, as controlling group velocity of light, giant Kerr nonlinearity, optical bistability. A special attention of the review also gives for analytical interpretations of EIT spectrum, its dispersion and related applications such as EIT enhanced Kerr nonlinearity and optical bistability to give physics insight. From experimental point of view, a latest development for measuring multi-EIT spectrum and its dispersion in hot medium is presented and compared to theoretical analytical representations.

“…The advent of EIT [4] offers coherent media of vanished resonant absorption [5][6][7][8] and controllable giant Kerr nonlinearity [9][10][11]. Wang et al performed a direct measurement of self-Kerr nonlinear coefficient in a three-level lambda EIT medium in the presence of Doppler broadening by using a cavity scanning technique.…”

We study optical bistability (OB) in a controllable giant self-Kerr nonlinear atomic gaseous medium placed in a unidirectional ring cavity. The medium is coherently excited by strong controlling field and a weak probe laser field under electromagnetically induced transparency (EIT) and Doppler broadening. In a weak field limit of the probe light, an analytic OB equation for the probe light field is derived as an analytic function of parameters of the controlling field and temperature of the medium. It is shown that OB characters can be manipulated with the parameters due to the controllable properties of the self-Kerr nonlinearity. Furthermore, enhancement of the Kerr nonlinearity reduces the switching intensity threshold and width of the OB.
