Nonlinear Optical Effects in Organic Materials

摘要: The physics of nonlinear optical processes in organic materials relates to the molecular nature these systems and their unique chemical bonding. In this article, concepts are discussed at both microscopic bulk levels. Experimental methods studies nonlinearities described. Ultrafast techniques measure dynamics resonant third-order response along with contributions from various photoexcitation materials. Organic also exhibit a large variety carriers which can be either photoexcited or produced by doping. role relation nonlinearity is examined. regard device processes, an waveguide bistability Fabry-Perot etalon discussed. To conclude, discussion current status, future directions research exciting opportunities new multidisciplinary field effects presented.
