Abstract Optical second-harmonic generation. Stimulated Raman scattering. Self-focusing of light. The theory of non-linear optical effects is based on Maxwell’s equations and the material equations. From Maxwell’s equations one can obtain the wave equation (see Chapter 22).

Functionalized optical fibers for non-linear optics
Asia Communications and Photonics Conference 2016, 2016The state of the art of functionalized optical fibers will be reviewed. The discussion will include, but not be limited to, semiconductor optical fibers and fibers that have been integrated with low-dimensional materials.

Contemporary Physics, 1964
Abstract It is shown that non-linear optical phenomena will occur when high intensity light beams interact with matter. Such light beams have become available with the invention of lasers. A review of the experiments performed with lasers to exhibit non-linear effects is given.

Electron crystallography and non-linear optics
Microscopy Research and Technique, 1999Electron crystallography can be used to obtain specific information about molecular parameters such as the polarisability, dipole moment, and hyperpolarisability. In this, work we show how a combination of quantum mechanics and simulation methods can be used to solve several unknown organic structures and how the calculated molecular parameters can be ...

We have assumed in previous chapters that the electric current density and polarization in a medium are linear functions of the electric field of an electromagnetic wave. The linear optical properties are defined in terms of these functions. The justification for the linear theory is that the applied field is much less than the atomic fields which act ...

In this paper we describe and thoroughly discuss three reported experiments in quantum optics (QO) involving interferometers and non-linear crystals. We show that by using a graphical method and an over-simplified model of the parametric down-conversion ...

Polymeric Non-Linear Optical Waveguides
SPIE Proceedings, 1988A particularly useful format for organic non-linear optical materials is that of a planar or stripe waveguide so that the materials can be utilised in integrated optical devices. The materials then have requirements placed upon them in addition to the need for high x2 or x3 coefficients: they must also be depositable in films of well controlled ...

Non‐linear optical and electro‐optical polymers
Recueil des Travaux Chimiques des Pays-Bas, 1991AbstractIn this review, we present a general overview of organic molecules and materials for non‐linear optics, with emphasis on materials for frequency doubling and for the Pockels or electro‐optic effect. After a short introduction on the molecular basis of second‐order non‐linearity, we shall discuss the relevant materials aspects of three important

Non-Linear Optical Processes in Optical Fibres
1988Optical fibers are now the transmission medium of choice for many applications and there is an increasing interest in optical signal processing using electric, optical, magnetic or acoustic fields. In particular Tall-optical1 signal processing, the optical control of optical signals, is a preferred approach as it circumvents the need of transducers for

Non-linear acousto-optic imaging
Biomedical Topical Meeting, 2002To improve both the contrast and the spatial resolution of acousto-optic imaging, we use the second-harmonic signal. We have found quadratic variation of this signal with the acoustic pressure, and we show that it induces a strong reduction of the modulation zone.
