Nonlinear optical (NLO) systems are arrangements where the interaction between light and matter is significantly altered by the intensity of the light itself. In these systems, the material's response—typically its electrical polarization—is not a linear function of the incident electric field, leading to phenomena like frequency conversion and self-focusing. Core Concepts and Historical Context Systems use NLO for all-optical signal processing ,

The field emerged in at the University of Michigan following the invention of the laser. It is governed by the nonlinear susceptibility tensor ( χ(2)chi raised to the open paren 2 close paren power χ(3)chi raised to the open paren 3 close paren power In these systems

High-quality nanophotonic devices enhance nonlinear effects by confining light into extremely small volumes, enabling high efficiency at lower powers.
