Controlling the shape and direction of hysteresis cycle in an optical bistability system with three-level atoms

Abstract

We experimentally demonstrate ‘backward’ hysteresis loop in optical bistability from an optical ring cavity containing three-level (Λ-type) rubidium atoms. Switching from ‘backward’ to normal hysteresis loop can be controlled by coupling field and cavity detuning.

Hysteresis loop with controllable shape and direction in an optical ring cavity

Amitabh Joshi, Wenge Yang, Min Xiao

We have experimentally observed a ``backward'' (clockwise rotating) hysteresis cycle in the system of an optical ring cavity containing three-level ($\ensuremath{\Lambda}$-type configuration) rubidium atoms. The shape and direction of the observed hysteresis cycles can be easily controlled with experimental parameters. Such an interesting phenomenon is caused by the greatly modified absorption, dispersion, and nonlinear optical properties of the three-level atomic medium, due to the induced atomic coherence.

Dynamical hysteresis in optical bistability of a three-level atomic system

Amitabh Joshi, Wenge Yang, Min Xiao

We have experimentally investigated the dynamical hysteresis cycles in the optical bistability from the vapor of rubidium atoms contained in an optical cavity by changing the sweeping frequency of the input cavity field. The shape, width and direction of the hysteresis cycle are sensitive functions of the sweeping frequency parameter.

Experimentally controlled optical bistability and multistability in a three-level atomic system

Amitabh Joshi, Min Xiao

Optical bistability and multistability are experimentally demonstrated in an optical ring cavity containing three-level (Λ-type) rubidium atoms. They are sensitive to the induced atomic coherence and can be controlled by coupling field and atomic density.

Dynamical hysteresis in a three-level atomic system

Amitabh Joshi, Wenge Yang, Min Xiao

We have experimentally investigated dynamical hysteresis behavior by changing the sweeping frequency of the cavity input field in the optical bistability of rubidium atoms (in a three-level atomic-type configuration) inside an optical cavity. The shape, width (or area), and direction of the hysteresis cycle are sensitive functions of the sweeping frequency for such an optical bistable system.

Controlling optical bistability in a three-level atomic system

We have experimentally studied the optical bistable behavior in an optical ring cavity filled with a collection of three-level $\ensuremath{\Lambda}$-type rubidium atoms, interacting with two collinearly propagating laser beams. The bistability so observed is very sensitive to the induced atomic coherence in this electromagnetically induced transparency system or consequently to the altered nonlinearity in the system and, thus, can easily be controlled by changing the intensity and the frequency detuning of the coupling field.

Optical Multistability in Three-Level Atoms inside an Optical Ring Cavity

Amitabh Joshi, Min Xiao

Optical multistability in an optical ring cavity filled with a collection of three-level Lambda-type rubidium atoms has been experimentally demonstrated. The observed multistability is very sensitive to the induced atomic coherence in the system and can evolve from a normal bistable behavior with the change of the coupling field as well as the atomic number density. The underlying mechanism for the formation of such multistability is also discussed.
