“…Nonlinearity and feedback are the main features required for making a bistable device. The optical bistability (OB) can be extrinsic if an external feedback is present, as in experiments with cavities, or intrinsic when it occurs at the atomic scale [2]. Bistable devices are important in the digital circuits and in communications, signal processing and computing.…”

In this work a theoretical model treating the optical bistability in a two state dissipative atomic medium inside a Fabry-Perot cavity is presented. The model is based on a semiclassical point of view to explain the field-matter interaction. The atoms of the medium are described by the "quantum polarization equation of motion" while the field is described by the "classical Maxwell's field equations". Applying the boundary conditions to the fields inside the Fabry-Perot cavity, the occurrence of optical bistability is deduced between the incident field intensity and both the intracavity and transmitted field intensities. Also the effect of building standing and nonstanding waves inside the cavity on bistability is discussed.

Magnetic-field-induced optical bistability in multifunctional Gd_2O_3:Er^3+∕Yb^3+ upconversion nanophosphor

et al. 2010

The effect of an external magnetic field (0-1 T) on the upconversion emission (lambda(exc)=976 nm) of Gd(2)O(3):Er(3+)Yb(3+) nanocrystalline phosphor has been studied. Optical bistability (hysteresis behavior in the intensity of the optical emission) for different transitions of the Er(3+) ion has been observed for a complete cycle of the magnetic field between 0 and 1 T. The phosphor shows paramagnetic behavior, consistent with the presence of Gd(3+) ions, at room temperature. Interaction between induced magnetization in the Gd(2)O(3) host and the intrinsic magnetic moment of the nanosized clusters of Er(3+) and Yb(3+) ion pairs is proposed to be responsible for the hysteresis behavior.
