Mathematical frontiers in optical solitons [PDF]
Solitons are localized concentrations of field energy, resulting from a balance of dispersive and nonlinear effects. They are ubiquitous in the natural sciences. In recent years optical solitons have arisen in new and exciting contexts that differ in many ways from the original context of coherent propagation in a uniform medium.

An electro‐templating strategy directs the relaxation of cholesteric finger loops into discrete concentric rings whose geometry is electrically programmed. The photopolymerized structures retain the topological defect pattern and, upon heating, show reversible, castle‐like surface modulation.

In this study, we examine the conformal space-time fractional nonlinear Schrödinger (NLS) model and derive several new closed-form optical soliton solutions using an interoperable auxiliary-equation method.

Stokes solitons in optical microcavities [PDF]
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 ...

Advancing Energy Materials by In Situ Atomic Scale Methods
Progress in in situ atomic scale methods leads to an improved understanding of new and advanced energy materials, where a local understanding of complex, inhomogeneous systems or interfaces down to the atomic scale and quantum level is required. Topics from photovoltaics, dissipation losses, phase transitions, and chemical energy conversion are ...

With the advancement of 6G communications, high‐precision radar, and advanced imaging technologies, there is a growing demand for compact, high‐performance light sources capable of generating high‐frequency radio waves (millimeter‐wave and terahertz waves). This article systematically introduces how to efficiently generate these high‐frequency waves on

Dynamical Optical Structure Solutions of the Time-Fractional Chen-Lee-Liu Equation
In this article, we utilize the conformable fractional (CF) derivative to investigate the analytically innovative soliton solutions for the time-fractional nonlinear perturbed Chen-Lee-Liu (CLL) equation in optical fibers. An essential governing equation

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

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.
