Silica Fiber with Large and Thermodynamically Stable Second Order Optical Nonlinearity
… molecules, strong and thermodynamically stable SHG can be obtained. Our experiments also provide strong evidence for the theory. Start from the basic Maxwell equation, we derive the SHG efficiency that the excited power translates into the SHG signal. According to the SHG efficiency equation, a …

Second-harmonic generation as a probe of chemically modified Si(111) surfaces and the initial oxidation of hydrogen terminated Si(111)
Optical second-harmonic generation (SHG) is used to probe Si(111) surfaces with covalently attached monolayers. The surfaces are prepared using wet chemical modification to form -H, -C 10 H 21 (decyl) and -O-C 10 H 21 (decyloxy) monolayers. The SHG efficiency for these surfaces as well as a Si(111) …

Synthese und Charakterisierung von ferroelektrischen Xerogelen
… especially second-harmonic generation (SHG). The sol-gel method is a wet-chemical technique and the chemical reaction starts upon addition water to a solution of an alcoxide, alcohol and a catalyst. Colloidal nanoparticles are formed and dispersed in the solution. The particles …

Plasmonic Enhancement of Nonlinear Optical Responses by Gold Nanorods
… light, it is possible to greatly enhance the SHG efficiency. To demonstrate this, the surface of the gold nanorods was functionalized with a nonlinear-optical (NLO) polymer, PCBS, via the layer-by-layer method and deposited on a polymer thin film created on a glass substrate using the ionic …
