Optical Rotatory Dispersion [PDF]

open access: possibleNature, 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.

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.

Dispersion in Optical Waveguides

1977
By far the most important characteristic of a fiber, for its use in optical communications, is the spread of a pulse as it propagates through the fiber. The smaller the pulse dispersion, the greater the information carrying capacity. For example, if the pulse spread is reduced from 1000 to 1 nsec, the transmission capacity would increase from 1 million

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.

Simple dispersion law for arbitrary sequences of dispersive optics [PDF]

open access: possibleApplied Optics, 2010
We give a simple general formula for the total angular dispersion due to multiple arbitrary dispersive elements in a series. It is simply the sum of the individual elements' angular dispersions but with each divided by the total spatial magnification afterward (or, equivalently, multiplied by the total angular magnification afterward).

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 ...

Precompensation for optical dispersion

SPIE Proceedings, 2005
Transport fiber deployed in metro and long-haul networks exhibit chromatic dispersion which if not addressed closes the receive eye. At 10Gbps line rates, dispersion management strategies are required to allow reaches to surpass their dispersion limited values. Several solutions exist which resolve this limitation. A survey of these is presented. Since

Optical Dispersion in Zinc Oxide

Physica Status Solidi (a), 1983
Radio-frequency reactively-sputtered films of c-oriented polycrystalline zinc oxide exhibit optical dispersion which differs significantly from published data on single crystal material. A model is developed which satisfactorily describes the bulk material, including birefringence and temperature dependence of dispersion, based on empirical absorption ...

Subwavelength Artificial Structures: Opening a New Era for Engineering Optics

Advances in Materials, 2018
In the past centuries, the scale of engineering optics has evolved toward two opposite directions: one is represented by giant telescopes with apertures larger than tens of meters and the other is the rapidly developing micro/nano‐optics and ...
