چکیده
A new type of optical bistability mediated by pho~ion and virtual exciton coupling is suggested for polymers. Numerical results with parameters pertaining to polydiacetylene-toluene-sulfonate are given as an illustration. The stability of the steady-state solution is examined, and the physical mechanism responsible for the bistability is discussed. 1988 PACS numbers. 42.65.-k, 42.65.pc, 36.20.-r, 78.65.Hc * On leave of absence from the Shanghai Institute of Metallurgy, Academia Sinica, Shanghai, People's Republic of China.

Transient dynamics in excitonic optical bistability in polymers.
Transient behavior in optical bistability mediated by phonon mode and virtual exciton coupling is studied for an electron-phonon coupling system such as a polydiacetylene-toluene-sulfonate. Numerical calculations are used to analyze the evolution between bistable states, and novel switching behavior and Rabi oscillations are found. * Also with the Department of Chemistry 1990 PACS Numbers: 42.6...
متن کاملOptimization of Bistability in Nonlinear Chalcogenide Fiber Bragg Grating for All Optical Switch and Memory Applications
We solve the coupled mode equations governing the chalcogenide nonlinear fiber Bragg gratings (FBGs) numerically, and obtain the bistability characteristics. The characteristics of the chalcogenide nonlinear FBGs such as: switching threshold intensity, bistability interval and on-off switching ratio are studied. The effects of FBG length and its third order nonlinear refractive index on FBG cha...
متن کاملAnomalous optical bistability and robust entanglement of mechanical oscillators using two-photon coherence
We analyze the optical bistability and the entanglement of two movable mirrors coupled to a two-mode laser in a doubly resonant cavity. We show that in stark contrast to the usual red-detuned condition for observing bistability in single-mode optomechanics, the optical intensities exhibit bistability for all values of cavity laser detuning due to intermode coupling induced by two-photon atomic ...
متن کاملCavity-enabled self-electro-optic bistability in silicon photonics.
We propose a new type of bistable device for silicon photonics, using the self-electro-optic effect within an optical cavity. Since the bistability does not depend on the intrinsic optical nonlinearity of the material, but is instead engineered by means of optoelectronic feedback, it appears at low optical powers. This bistable device satisfies all the basic criteria required in an optical swit...
متن کاملTheory of Nonlinear s-Polarized Phonon-Polaritons in Multilayered Structures
A theory is presented for the dispersion relations of the nonlinear phonon-polaritons arising when phonons are coupled to the electromagnetic waves in multilayered structures of nonlinear materials. The calculations are applied to a multilayered structure consisting of a thin film surrounded by semi-infinite bounding media where each layer may have a frequency dependent dielectric function and ...
