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.

Material dispersion in optical fibers

Applied Optics, 1979
A three-parameter description of optical fiber material dispersion is proposed which fits the available data and reveals the key roles played by bond length, lattice structure, chemical valence, average energy gap, and atomic mass. Using broadly applicable trends in electronic and phonon oscillator strengths, simple expressions are deduced for material

Optical Dispersion by Wannier Excitons

Physical Review Letters, 1995
An analytical expression of the complex dielectric constant of Wannier excitons is obtained, which includes exactly the contributions of all bound and unbound states. It allows an improved description of the excitonic influence on the optical properties of semiconductors near the band gap, especially with respect to dispersion effects.
