Dispersive Optical Bistability with Fluctuations

Physical Review A, 1981
We consider the phenomenon of dispersive optical bistability as an example of a non-equilibrium steady state lacking detailed balance. The Fokker Planck equation for the transmitted electromagnetic field is derived. For a special case of parameters we present an exact solution of the stationary distribution.

Bright and dark optical solitons for (2+1)-dimensional Schrödinger (NLS) equations in the anomalous dispersion regimes and the normal dispersive regimes

Optik (Stuttgart), 2019
We operate the variational iteration method (VIM) for obtaining bright and dark optical solitons for (2+1)-dimensional nonlinear Schrodinger (NLS) equations, that appear in the anomalous dispersion regimes and the normal dispersive regimes respectively ...

Optical resonator with negative dispersion

Optics Letters, 1984
Analysis of an optical ring resonator consisting of a prism and two mirrors demonstrates that such a resonator can have adjustable dispersion of either sign. The dispersion is proportional to the second derivative of the optical path length in the resonator with respect to wavelength.

Optical biosensor with dispersion compensation

Optics Letters, 2005
Dispersion limits performance in many optical systems. In surface plasmon resonance (SPR) biosensors, the sensing area is an optical element in which the dispersion depends on the effective refractive index of the biochemical compounds to be measured.

Optical Rotatory Dispersion

Nature, 1926
SINCE the publication of Prof. T. M. Lowry's article in NATURE of February 20, 1926, p. 271—an article which, I observed, drew a gentle remonstrance from Prof. Armstrong in the issue of April 17—I have felt that some rejoinder was desirable, but was held back by the fact that adequately to criticise Prof.

Optical rotatory dispersion of carotenoids

J. Chem. Soc. C, 1969
The o.r.d. curves of ca. 40 carotenoids have been measured, chiefly in dioxan, over the range 400–200 nm. The chromophore in all cases is a conjugated polyene system which is perturbed by one or two chiral end-groups. The curves are analysed in terms of the simple additivity of the effects of end-groups, and the absolute configurations of several ...

Optical rotatory dispersion of sugar

Carbohydrate Research, 1966
Abstract The direction of optical rotatory dispersion curves in the far-ultraviolet spectral region has been related to configuration and conformation of the ring forms of sugars. Rules have been proposed for the study of ketoses, higher-carbon sugars, and furanoid forms of sugars.
