In this paper, we proposed a cavity containing an intracavity medium of five-level double-ladder-type atoms with electromagnetically induced transparency to enhance Goos-Hänchen shifts of reflected and transmitted light beams. The dependence of the Goos-Hänchen shifts has been analyzed. It is shown that Goos-Hänchen shifts can be controlled by modifying the intensity and detuning of the coherent control field without changing material and the structure of the dielectric interface. This work has considerable potential for applications such as optical devices in information processing, flexible optical-beam steering and alignment, optical sensors and optical switches.

“…Recently, many studies have been interested in using an external magnetic field to control absorption and dispersion [34][35][36][37][38][39], light propagation [40,41], Kerr nonlinearity [42], and optical switching and bistability [43,44]. In most of these studies, the external magnetic field is utilized to separate the degenerate sublevels of the ground-state via the Zeeman effect and form the three-level Λ-type scheme.…”

Optical properties including absorption, dispersion, group index, Kerr nonlinearity, and optical bistability of a three-level V-type atomic medium have modified by varying an external magnetic field. By changing the magnitude or the sign of the external magnetic field, the transparency window with normal dispersion transfers to the enhanced absorption with anomalous dispersion at the line center, and hence the light propagation switches between subluminal and superluminal modes. The magnitude and the sign of the Kerr nonlinearity are controlled with the strength and the sign of the magnetic field. As a consequence, the behaviors of optical bistability are also made to appear or disappear when switching on/off the magnetic field. Moreover, the threshold intensity and width of optical bistability are also changed by the magnetic field and the coupling field. The results can be used to control the working characteristics of applied devices and study the related effects.

“…Other studies on the EIT in the multi-level system based on velocity selection [47][48][49][50], in nanofiber [51,52], and in the presence of the magnetic field [53][54][55] are proposed most recently. Some research groups used such controlling fields to control the optical properties of EIT medium at multiple frequencies, e.g., manipulation of the group velocity [42,46,[56][57][58], Kerr nonlinearity [59][60][61], OB [62][63][64][65], all-optical switching [66][67][68][69], and controllable entanglement of lights in a five-level system [70], etc.…”

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.
