Chirped gap solitons in fiber Bragg gratings with polynomial law of nonlinear refractive index

Journal of the European Optical Society-Rapid Publications, 2023
The objective of the present study is to examine the behaviors of chirped optical solitons in fiber Bragg gratings (BGs) with dispersive reflectivity. The form of nonlinear refractive index represents polynomial law nonlinearity.

Stokes solitons in optical microcavities [PDF]

Conference on Lasers and Electro-Optics, 2016
Solitons are wavepackets that resist dispersion through a self-induced potential well. They are studied in many fields, but are especially well known in optics on account of the relative ease of their formation and control in optical fiber waveguides. Besides their many interesting properties, solitons are important to optical continuum generation, in ...

Optical solitons in birefringent fibers with the generalized coupled space–time fractional non-linear Schrödinger equations

Frontiers in Physics, 2023
The nonlinear Schrödinger (NLS) equation is an ideal model for describing optical soliton transmission. This paper first introduces an integer-order generalized coupled NLS equation describing optical solitons in birefringence fibers.

Deterministic Fiber‐Optic Spectral Engineering Enables Three‐Color Multiplexed Two‐Photon Microscopy

Laser &Photonics Reviews, EarlyView.
A simulation‐guided spectral‐engineering framework maps the nonlinear parameter space of a fiber laser platform to identify balanced three‐band excitation states. The resulting 960, 1080, and 1175 nm femtosecond pulses deliver nJ‐level energies for low‐cross‐talk chromatically multiplexed two‐photon microscopy.

Broadband Parametric Amplification in AlGaAs‐on‐Insulator Nanowaveguides

Laser &Photonics Reviews, EarlyView.
Harnessing the exceptional nonlinearity of AlGaAs‐on‐insulator nanowaveguides, four‐wave‐mixing parametric amplification achieves a record net on‐chip gain of 56 dB and a gain bandwidth exceeding 415 nm at telecom wavelengths. These results establish AlGaAsOI as a powerful platform for compact, high‐performance integrated nonlinear optical ...

Quiescent optical solitons with Kudryashov’s law of nonlinear refractive index

Results in Physics, 2023
The present study reports quiescent optical solitons for Kudryashov’s proposed form of self-phase modulation with quintuple nonlinearity having two power-law parameters. The solitons were retrieved with the usage of enhanced Kudryashov’s algorithm.

Solitons in optical fibers

, 1989
In the preceding chapter it was shown that, under ideal conditions, a light wave in a dielectric material would form an envelope soliton. However, in a real three-dimensional fiber, the light wave propagates with finite loss. In this chapter, we discuss the practical conditions needed for an optical pulse to become a soliton in a dielectric waveguide.

Formation of Optical Fractals by Chaotic Solitons in Coupled Nonlinear Helmholtz Equations

Fractal and Fractional
In the present research work, we construct and examine the self-similarity of optical solitons by employing the Riccati Modified Extended Simple Equation Method (RMESEM) within the framework of non-integrable Coupled Nonlinear Helmholtz Equations (CNHEs).
