Non-Linear Optical Properties of Si Nanocrystals
3rd IEEE International Conference on Group IV Photonics, 2006., 2006Nonlinear optical refraction and absorption have been measured on Si nanocrystals grown by plasma-enhanced- chemical-vapour-deposition. Strong nonlinearities were found at 830 nm and at 1552 nm.

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).

The Orientational Optical Non – Linearity of Liquid Crystals
Molecular Crystals and Liquid Crystals, 1981Abstract The cubic optical non-linearity of smectic liquid crystals (SLC) conditioned by director reorientation and layer structure deformation under the action of a light field is calculated. The strongest effects for smectic C phases are conditioned by the c-director turning without layer structure deformation.

Non‐linear optical microscopy of kidney tumours
Journal of Biophotonics, 2013AbstractThe unregulated cancer cell growth leads to strong alterations in morphology and composition of the tissue. The combination of coherent anti‐Stokes Raman scattering, two‐photon excited fluorescence and second harmonic generation enables a high resolution imaging with strong information on tissue composition and can then provide useful ...

Non-linear optical properties of cyanine systems
Synthetic Metals, 2001In this paper we present ab initio calculations for the evaluation of molecular hyperpolarizabilities of symmetric cyanine molecules. The influence on the electronic properties of the presence of a counterion is discussed taking into account the relative position of the molecule and the counterion itself.

The Basics of Non-Linear Optics
2014At a semi-classical level, the main analytical electromagnetic field theory tools were first used to describe the non-linear effects of light-light coupling as a basic cause of nonlinear optical phenomena and applications.

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

Noble metal nanoclusters belong to nonscalable regime in which each atom counts. They exhibit molecular like electronic transitions, due to quantum confinement effects, which are strongly influenced by structure. These systems have potential for applications in biosensing and bioimaging, based on their unique optical, electronic and structural ...
