Threshold-free optical bistability due to giant nonlinearity of resonance absorption in crystals containingFAcenters

Abstract

An analysis is made of a polarization optical bistability in crystals containing FA centers and placed in a resonator. The bistability is due to the possibility of amplification of fluctuations of the polarization of radiation in such crystals and in practice has no threshold in respect of the radiation intensity. An analysis is made of the ranges of values of the parameters of a doped crystal and of a resonator in which this bistability can be observed. The analysis is carried out for ring and Fabry–Perot resonators.

Effect of Optical Feedback on Self‐Induced Change of Light Polarization in Cubic Crystals with Directions Instable for Polarization

A. Brodin, Sergey A. Boiko, Mykhailo Ya. Valakh +1 more

Abstract Polarization optical bistability (POB) in crystals with FA‐centers mounted into a Fabry‐Perrot cavity is analysed. This type of optical bistability is caused by amplification of fluctuations of light polarization in crystals under consideration and has no threshold on radiation intensity. The range of parameters is found for impure crystals and cavity under POB conditions.

Dichroic optical bistability in a nonlinear Fabry–Perot interferometer

M. I. Dykman, Georgiy G. Tarasov

It is shown that a new type of optical bistability may occur in a Fabry–Perot resonator containing a nongyrotropic cubic crystal. This instability is due to an anisotropy of the nonlinear resonance absorption in the crystal. The explicit conditions for the establishment of dichroic optical bistability are determined for cases of two-photon absorption and resonance absorption by reorientable impurity centers.

Optical bistability associated with orientational nonlinearity of liquid crystals

Boris Ya Zel'dovich, Nelson V. Tabiryan

An analysis is made of nonlinear optical phenomena associated with a change in the orientation of the director of a liquid crystal induced by an optical field and resulting in optical bistability. The usual configurations with a nonlinear Fabry-Perot resonator and several other configurations are considered. Bistable cells with cholesterics are proposed: in these cells the nonlinearity is associated with the absorption of the incident and reflected light and is related—via the temperature of the cell—to the cholesteric helix period. Devices are considered in which switching from one state to another takes place as a result of a change in radiation parameters (such as the frequency or polarization) other than the power.

Range of existence of optical multistability in a resonator with an optically active medium

M. I. Dykman, Vladimir Makarov, A. V. Matveeva

Optical bistability in resonators containing a nonlinear gyrotropic isotropic medium is analyzed by studying the dependence of the bifurcation intensity of the incident radiation on its ellipticity. It is found that if the gyrotropy is weak, this dependence may have symmetry-induced singular points or turning points. The stable radiation states in the resonator formed near a singular or turning point differ in respect of the polarization and are due to the evolution of the polarization instability. Bifurcation curves are plotted for a ring resonator containing a medium with a cubic nonlinearity. The form of these curves changes appreciably as the gyrotropy is increased. The change in the resonator transmission accompanying changes in the gyrotropy is studied.

Theoretical analysis of optical bistability of a faraday medium

Masao Hirano

Abstract An optical bistable device can be useful not only for optical memory but also for optical sensing by using its binary signal process characteristics. In this case, if a nonlinear Faraday medium is used in the optical bistable device, some interesting features can be obtained as already shown by the present author. Those unique characteristics are that, by controlling the polarization direction by an external magnetic field, a multiple interference can also be controlled not only by the phase associated with an optical path variation but also the polarization direction. This paper describes a theoretical analysis of the fluctuation of transmission and reflection as a function of an absorption in a medium besides the incident intensity reduction and discusses the bistability characteristics and the threshold values against the parameters. It is shown that the control of the bistable function, the realization of a low threshold value, and the increase of a discontinuous power variation ratio (= optical intensity ratio between on and off in the binary signal process) at the threshold value are accomplished as the result of the introduction of the external magnetic field control method. Therefore, it can be concluded that a Faraday medium is very useful for an optical bistable device.

Optical polarization multistability

G. G. Adonts, G. P. Dzhotyan, Eghine G. Kanetsyan

A theoretical investigation is made of the polarization characteristics of the optical polarization and amplitude multistability of a Fabry?Perot interferometer filled with a nonlinear resonant medium. In the case of linear polarization of the incident radiation it is shown that an amplitude hysteresis differs considerably from a hysteresis predicted by a scalar theory; moreover, the degree of polarization exhibits a hysteresis. A calculation is made of the critical input intensity of elliptically polarized radiation for which the ellipticity at the output rises strongly even when it is negligible at the input.
