Paper Abstract

This paper reviews two emerging approaches towards new materials and related device technologies for nonlinear photonic applications. Hybrid organic-inorganic sol-gel materials are shown to be meeting material engineering requirements, with the electrically poling of Disperse Red1- like chromophores grafted to a syloxane chain exhibiting a remarkably high non resonant second-order nonlinearity together with long-term orientational stability. Furthermore, an all-optical poling method based on the photoinduced orientation of molecules in various matrices, appears as an appealing alternative to the traditional electric field poling, capable to circumvent its intrinsic limitations such as the necessity of a dipolar chromophore. We have experimentally demonstrated the possibility to implement a macroscopic multipolar organizational scheme by way of purely optical photoinduced processes. Adequate choice of the polarization states of fundamental and harmonic <<write>> beams will leave a permanent imprint of any desired symmetry pattern onto the (non)linear material.
