Second harmonic generation in poled polymer films
TL;DR: In this paper, the second harmonic coefficient (d33 = 6.0±1.3×10−9 esu, at 1.58 μm wavelength) and the poling process were described by a thermodynamic model that was developed.
Journal ArticleDOI

Nonlinear optical materials and devices
TL;DR: An electrooptic or optical parametric device comprises a noncrystalline second order optically nonlinear element and means for providing an optical input to and an optical output from said element wherein said element comprises an organic molecule having second order optical susceptibility incorporated in a directionally oriented manner in an optically clear glassy polymer as discussed by the authors.
Journal ArticleDOI
Exceptional second-order nonlinear optical susceptibilities of quinoid systems
TL;DR: In this article, a new class of organic quinoid systems possessing intrinsically large, nonlinear second-order optical susceptibilities has been developed based on theoretical calculations and dc-induced second-harmonic generation measurements of the molecular second order susceptibilities β.
