TLDR
It is shown that processes such as second-harmonic generation and subsequent downconversion, and parametric mixing in general, can lead to large field-dependent phase shifts for the input beams under a variety of conditions.Abstract:

Discrete Solitons in Optics
Falk Lederer,George I. Stegeman,Demetri N. Christodoulides,Gaetano Assanto,M. Segev,Yaron Silberberg +5 more
TL;DR: In this article, the authors provide an overview of recent experimental and theoretical developments in the area of optical discrete solitons, which represent self-trapped wavepackets in nonlinear periodic structures and result from the interplay between lattice diffraction (or dispersion) and material nonlinearity.

Spatiotemporal optical solitons
TL;DR: In this article, an up-to-date survey of experimental and theoretical results in spatiotemporal optical solitons can be found, together with a review of the outstanding difficulties and open problems.

χ(2) cascading phenomena and their applications to all-optical signal processing, mode-locking, pulse compression and solitons
TL;DR: Cascading is the process by which the exchange of energy between optical beams interacting via second order nonlinearities leads to various effects such as nonlinear phase shifts, the generation of new beams, all-optical transistor action, the formation of soliton-like (solitary) waves, etc as mentioned in this paper.

Models of few optical cycle solitons beyond the slowly varying envelope approximation
Hervé Leblond,Dumitru Mihalache +1 more
TL;DR: In this article, the authors used the powerful reductive expansion method (alias multiscale analysis) to derive simple integrable and nonintegrable evolution models describing both nonlinear wave propagation and interaction of ultrashort (femtosecond) pulses.

Synthesis of Organic Salts with Large Second-Order Optical Nonlinearities
TL;DR: A series of organic salts, in which the cation has been designed to have a large molecular hyperpolarizability, has been prepared as discussed by the authors, which leads to materials with large powder second harmonic generation efficiencies, the highest of which is roughly 1000 times that of a urea reference.
