Symmetric Nonlinear Michelson Interferometer (SNMI) operating as optical bistable device has been theoretically investigated. The general output-input intensity relation is introduced for case the output signal transmitted through SNMI. The bistable characteristic (hysteresis) is calculated and presented for some cases the structural parameters were selected specifically.

On the basis of the input-output intensity relationship of the signal, this paper will evaluate and discuss the role of the position of the signal going into the Nonlinear Michelson Interferometer (NMI) and its influence on the bistable characteristics. From that results, the position of signal going into the NMI will be chosen, so that the interferometer acts as an optical bistability device.

n this work, we review recent research works concerning multiple EIT and some related applications such as controlling group velocity of light, giant Kerr nonlinearity, optical bistability. The special attention of the review is also on analytical interpretations of the results to give physics insight and suitable applications. From an experimental point of view, the latest development for measuring multiple EIT spectrum and its dispersion in hot medium is presented and compared to the theoretical analytical representations.

The results showed that the threshold intensity of OB in Λ-type system is much less than the other ones and the threshold intensity of OB in V-type system is the largest one. The analytical result is convenient to choose excitation configuration for experimental observations and related applications in photonic devices.

Optical bistability (OB) of an electromagnetically induced transparency (EIT) medium placed in a conventional unidirectional ring cavity is investigated numerically. The medium is excited by a coupling and probe laser lights via a five-level cascade scheme. It is shown that optical bistabe states with controllable switching threshold intensities and width are established simultaneously in three spectral regions corresponding to EIT windows. The current numerical result is compared to a previous analytical result showing influence of coherence terms neglected in the analytical model.
