We present an overview of nonlinear phenomena related to optical quadratic solitons—
intrinsically multi-component localized states of light, which can exist in media without …

Cascading is the process by which the exchange of energy between optical beams
interacting via second order nonlinearities (χ (2)) leads to various effects such as nonlinear …

Utilizing a type II interaction for second‐harmonic generation in a crystal of potassium titanyl
phosphate, we experimentally demonstrate the all‐optical action of a light modulator with …

We analyze squeezing of both the fundamental and harmonic fields undergoing traveling-
wave, second-harmonic generation (SHG) in second-order (χ (2)) nonlinear media. We take …

We show that, in the high wave-vector-mismatch (cascading) limit, the well-known paraxial
description of parametric frequency conversion in quadratic media entails effective lensing …

A comprehensive analytical approach to scalar and vectorial interaction in cascaded
quadratic nonlinearities is presented. Exact formulas for the intensity as well as the phase …

We demonstrate a novel approach to phase insensitive, all-optical steering and switching
based on an intensity-induced change in the propagation direction of multidimensional …

Based on processes involving the cascading of two successive second-order nonlinear
interactions, we show how novel, all-optical approaches to signal processing can be …

We use our recently developed beam-deflection technique to measure the dispersion of the
nondegenerate nonlinear refraction (NLR) of direct-gap semiconductors. The magnitude …
