Abundant excited optical breathers for a nonlinear Schrödinger equation with variable dispersion and nonlinearity terms in inhomogenous fiber optics

, 2020
Under investigation is a nonlinear Schrodinger equation with variable dispersion and nonlinearity coefficients in inhomogenous fiber optics. Through extending Darboux transformation method, an analytic breather solution with two free functions is ...

Ultralow Dispersion Multicomponent Thin‐Film Chalcogenide Glass for Broadband Gradient‐Index Optics

Advances in Materials, 2018
A novel photothermal process to spatially modulate the concentration of sub‐wavelength, high‐index nanocrystals in a multicomponent Ge‐As‐Pb‐Se chalcogenide glass thin film resulting in an optically functional infrared grating is demonstrated.

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.

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 ...

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

Dispersive two-photon optical multistability

Optics Letters, 1982
Within the mean-field approximation, an analysis of the two-photon equation of state predicts double optical bistability and tristability. When spatial dependence is included, a precise description of multistability for the Kerr regime and for higher intensities is given.
