Nonlinear optical effects occur when the response of a material to an electromagnetic field, such as light, is not directly proportional to the strength of that field. This means that as the intensity of the light increases, the properties of the material change in complex ways, leading to phenomena like frequency doubling and self-focusing. These effects are essential in the context of photonics and optical computing, as they allow for advanced manipulation of light, enabling faster and more efficient information processing.
