Six modules (Y1~Y6) containing Y-type s-triazine based derivatives were optimized using density functional theory at B3LYP/6-31+G* level. On the basis of the optimized structure, electronic absorption spectrum was calculated with TD-DFT(TDB3LYP/6-31+G*) and the second-order nonlinear optical properties (NLO) were calculated with finite field (FF) method and coded programs. The results indicated that these molecules had good nonlinear optical properties with 106 order of magnitude a.u. (10-27 esu) of 0 value. Introducing different electron groups to the end of the tri-branched chain of this derivative would cause different results. Introduction of strong electron donating group would make a relatively large increase of u thus improving their second-order nonlinear optical properties, and making this derivative a good non-linear optical material.

AbstractFerroelectric oxide thin films show considerable potential as electro-optic and non-linear optical materials. Of particular interest are the niobates such as strontium barium niobate and potassium niobate. The growth of these epitaxial oxide films by metal-organic chemical vapor deposition (MOCVD) has been investigated. This technique has yielded epitaxial thin films with excellent non-linear optical properties. Issues concerning the epitaxy of these thin films and its relationship to their optical and nonlinear optical properties are discussed.

A supra-molecular crystal, 1-[C6H13NH][18-crown-6][ClO4] monohydrate, has been reported to show reversible dielectric anomalies and nonlinear optical properties, which suggests that it could be conceived as the potential switchable dielectric and non-linear optical material.

AbstractThe linear and nonlinear optical properties of Ge-implanted fused-silica were examined and compared with Au- and Si-implanted samples. Samples as-implanted with 1.0 MeV Ge ions to a fluence of 3x1017 Ge.cm-2 exhibited relatively large non-linearities, |n2| ≤5x10-12 cm2/W, and fast relaxation times, ∼lps. In contrast, samples implanted with comparable fluences of Au ions exhibited smaller non-linearities, |n2| ∼1x10-13 cm2/W, and slower response times, ≥ 10ps. The non-linearity for Ge was much larger than that for samples as-implanted with Si.
