1 Introduction. Materials can exhibit a nonlinear optical response upon interaction with an electric field that is of the order of interatomic fields (10 5 –10 8 V/m) [].Whereas a nonlinear optical response of solids and liquids subjected to strong external DC electric fields was observed by John Kerr all the way back in [], the birth of modern nonlinear optics can perhaps be . Abstract In the current work, the nonlinear optical properties in GaAs/Ga 1−x Al xAs semiparabolic and parabolic quantum well (QW) with constant effective mass (CEM) and position dependent effective mass (PDEM) are estimated for different applied magnetic by: 1.

The book presents an introduction to the entire field of optical physics and specifically the area of nonlinear optics. Fundamental issues treated in the book include the electromagnetic origin of optical phenomena, the quantum mechanical description of the optical properties of matter, the role of spatial symmetries in /5(15). Nonlinear optics (NLO) is the branch of optics that describes the behaviour of light in nonlinear media, that is, media in which the polarization density P responds non-linearly to the electric field E of the light. The non-linearity is typically observed only at very high light intensities (values of atomic electric fields, typically 10 8 V/m) such as those provided by lasers.

Nonlinear optical properties of photonic crystals was found to be µm for AlGaAs and µm for GaAs respectively. As an optical limiter, AlGaAs showed the . His research interests include studies of nonlinear optical interactions, studies of the nonlinear optical properties of materials, the development of photonic devices including photonic biosensors, and studies of the quantum statistical properties of nonlinear optical interactions. Professor Boyd has written two books, co-edited two /5(15).
