Switching dynamics of spatial solitary wave pixels [PDF]

open access: yes, 1993
Separatrices and scaling laws in the switching dynamics of spatial solitary wave pixels are investigated. We show that the dynamics in the full model are similar to those in the plane-wave limit.

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 ...

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 ...

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.

Tunable Optical Bistability in One-Dimensional Photonic Crystal with a Nonlinear Defect Coupled by Graphene Sheets

open access: yesAdvances in Condensed Matter Physics, 2017
The optical bistability in one-dimensional photonic crystal (1DPC) with a nonlinear defect is investigated. It is demonstrated that, by introducing graphene layers into the nonlinear defect, the optical bistability in 1DPC can be changed significantly ...

Bistability in Microcavities with Incoherent Optical or Electrical Excitation

open access: yes, 2013
We consider a quantum well embedded in a zero-dimensional microcavity with a sub-wavelength grated mirror, where the x-linearly polarized exciton mode is strongly coupled to the cavity photon, while y-polarized excitons remain in the weak coupling regime.

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.

Impact of geometry and magneto-optical properties on field enhancement and optical bistability in core–shell nanoparticles

open access: yesJournal of Theoretical and Applied Physics, 2018
We study the interaction of electromagnetic field with two of the most tunable nanostructure geometries for nanoplasmonics including the magneto-optical nanoshell structure and the spheroidal geometry. We investigate the effect of combining both geometry

Broadband coherent perfect absorption by cavity coupled to three-level atoms in linear and nonlinear regimes

open access: yesNew Journal of Physics, 2021
A broadband coherent perfect absorption (CPA) scheme consisting of an optical resonator coupled with three-level atoms excited by single cavity mode is proposed and analyzed.
