Catenary optics: a perspective of applications and challenges

Journal of Physics: Condensed Matter, 2022
Catenary optics is an emerging direction of subwavelength optics, which is indispensable in describing the electric fields and dispersion property of coupled metallic subwavelength structures, and designing broadband high-efficiency geometric-phase ...

Wavelength dispersion of optical waveguides

Applied Optics, 1980
Coefficients that characterize the contribution to the total waveguide dispersion from guide geometry and from material dispersion are introduced. These are cast in terms of the normalized parameters of normalized frequency, asymmetry measure, and effective guide index.

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.

Optical rotatory dispersion of viruses

Journal of Molecular Biology, 1967
The optical rotatory dispersion spectra of the following 16 viruses were measured: T2, T2(gt), T4, T6, T6(gt), λc, λ(K), λ(C), X174, T5, T7, B3, MS2, f2, R17 and α. T2 ghosts and T2, λ(C), λ(K), T7 and X174 DNA's and R17 RNA were also measured. The effect of high concentrations of lithium chloride salts at neutral pH on the DNA molecule in solution was

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 Rotatory Dispersion [PDF]

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 sugar

Carbohydrate Research, 1966
Abstract Optical rotatory dispersion curves have been obtained for a series of oligosaccharides. The rotatory data for the oligosaccharides, over the spectral region 600−185 mμ, where in general agreement with the sum of the rotations of the constituent monomeric residues.

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.

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

Applied 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).
