Nonclassical correlated optical multistability at low photon level for cavity electromagnetically induced transparency

open access: yesNew Journal of Physics, 2022
We study the nonequilibrium dynamic behaviors in a driven-dissipative single-atom cavity electromagnetically induced transparency. The optical bistability and multistability beyond a Kerr nonlinearity are observed utilizing the optical Stark shift ...

Optical bistability for two-level atoms in a standing-wave cavity [PDF]

open access: yes, 1982
Observations of optical bistability are reported for a system composed of multiple atomic beams passing through a high-finesse optical cavity. Both the transmitted power and the intracavity fluorescent intensity have been recorded as functions of ...

Bistability effect in the extreme strong coupling regime of the Jaynes-Cummings model [PDF]

open access: yes, 2015
We study the nonlinear response of a driven cavity QED system in the extreme strong coupling regime where the saturation photon number is below one by many orders of magnitude.

Bistable Spin Currents from Quantum Dots Embedded in a Microcavity [PDF]

open access: yes, 2006
We examine the spin current generated by quantum dots embedded in an optical microcavity. The dots are connected to leads, which allow electrons to tunnel into and out of the dot.

Control of optical bistability and third-order nonlinearity via tunneling induced quantum interference in triangular quantum dot molecules

open access: yesAIP Advances, 2015
The optical bistability of a triangular quantum dot molecules embedded inside a unidirectional ring cavity is studied. The type, the threshold and the hysteresis loop of the optical bistability curves can be modified by the tunneling parameters, as well ...

Coherent control of intersubband optical bistability in quantum wells [PDF]

open access: yes, 2003
We present a study of the nonlinear intersubband (ISB) response of conduction electrons in a GaAs/AlGaAs quantum well to strong THz radiation, using a density-matrix approach combined with time-dependent density-functional theory. We demonstrate coherent

Thermo-optical bistability in silicon micro-cantilevers

open access: yesSciPost Physics, 2021
We report a thermo-optical bistability observed in silicon micro-cantilevers irradiated by a laser beam with mW powers: reflectivity, transmissivity, absorption, and temperature can change by a factor of two between two stable states for the same input ...
