Golden spiral photonic crystal fiber: polarization and dispersion properties [PDF]

open access: yes, 2008
A golden spiral photonic crystal fiber (GS-PCF) design is presented in which air holes are arranged in a spiral pattern governed by the golden ratio, where the design has been inspired by the optimal arrangement of seeds found in nature.

A Quantum Theory of Optical Dispersion [PDF]

open access: yesNature, 1922
When a theory is framed trying to explain a discrepant system of facts, it is a necessary process of thought to take some branch of the theory as more completely true than the rest, and to adjust the remaining parts in such a way that they will fit in with this base, though they may still conflict with one another.

Dynamics of Nonlinear Optics with Different Analytical Approaches

open access: yesFractal and Fractional, 2023
In this article, we investigate novel optical solitons solutions for the Lakshmanan–Porsezian–Daniel (LPD) equation, along with group velocity dispersion and spatio-temporal dispersion, via three altered analytical techniques.

Meta-optics for spatial optical analog computing [PDF]

open access: yesarXiv.org, 2020
Rapidly growing demands for high-performance computing, powerful data processing, and big data necessitate the advent of novel optical devices to perform demanding computing processes effectively.

Dispersive nonlinear geometric optics [PDF]

open access: yesJournal of Mathematical Physics, 1997
We construct infinitely accurate approximate solutions to systems of hyperbolic partial differential equations which model short wavelength dispersive nonlinear phenomena. The principal themes are the following. (1) The natural framework for the study of dispersion is wavelength ε solutions of systems of partial differential operators in ε∂.

Dispersion-managed soliton in optical fibers with zero average dispersion

open access: yes, 2000
The dispersion-managed (DM) optical system with step-wise periodical variation of dispersion is studied in the framework of path-averaged Gabitov-Turitsyn equation. The soliton solution is obtained by iterating the path-averaged equation.

On optical dispersion formulæ [PDF]

open access: yesProceedings of the Royal Society of London. Series A, Containing Papers of a Mathematical and Physical Character, 1908
In the half century that elapsed from the time when Cauchy published is memoirs on dispersion, the only measurements of refractive indices that ere available for the test of any theory were confined to the neighbourhood of the visible spectrum. They extended from somewhat beyond 0·2 µ to bout 0·8 µ

The connection between the peaks in velocity dispersion and star-forming clumps of turbulent galaxies

open access: yes, 2017
We present Keck/OSIRIS adaptive optics observations with 150-400 pc spatial sampling of 7 turbulent, clumpy disc galaxies from the DYNAMO sample ($0 ...

Nonlinear wavelength conversion in photonic crystal fibers with three zero dispersion points

open access: yes, 2010
In this theoretical study, we show that a simple endlessly single-mode photonic crystal fiber can be designed to yield, not just two, but three zero-dispersion wavelengths.

Optical Chirality in Dispersive and Lossy Media [PDF]

open access: yesPhysical Review Letters, 2018
Several dynamical properties such as energy, momentum, angular momentum, and optical helicity have been recently reexamined in dispersive and lossless media. Here, we address a parallel derivation for the optical chirality, extending it so as to include dissipative effects as well.
