Abstract We derive propagation equations modeling third-order susceptibility-induced nonlinear interaction and linear mode coupling in waveguides. We model material susceptibility with Raman and electronic response which include approximations suited for optical communications. We validate our model by comparing numerical integration of the propagation equations to continuous wave measurements of a silicon on insulator waveguide.

In this study, 8-(4-methoxyphenyl)-6-oxo-3-p-tolyl-6H-pyrido[1,2-b][1,2,4]triazine-7,9-dicarbonitrile (A) was prepared and then the nonlinear optical properties of this compound, including nonlinear refractive index (n2) and nonlinear absorption coefficient (β) were measured using Z-scan technique by continuous wave laser diode at wavelengths of 405 and 532 nm. At wavelength of 532 nm, by increasing the incident intensity a switch over from saturable absorption (SA) to reverse saturable absorption (RSA) was observed. The results showed that the nonlinear optical properties of this compound depend on the wavelength. It was also observed that with decreasing incident intensity, the thermal nonlinear refractive coefficient increased accordingly, while its thermo-optic coefficient decreased. In addition, the third-order susceptibility of this compound in wavelength of 532 nm was obtained higher than 405 nm.

Nanoparticles Of Silver

Nanoparticles of silver-embedded indium oxide thin films have been prepared on glass and silicon substrates. Silver concentration were 3 wt.% and 5 wt.% as measured by X-ray fluorescence. X-ray diffraction reveals that indium oxide of these samples remains amorphous even after pre-annealing at 400°C. The optical absorption of the samples manifests the surface plasmon resonance (SPR) phenomena, which varies with Ag content. The Ag nanoparticles radius was estimated with Mie classical theory by using the SPR data analysis. The nonlinear optical properties of films on glass substrate were investigated using z-scan technique. Under cw excitation the films exhibit large reverse saturation absorption and negative nonlinearities. The real and imaginary parts of third order susceptibility of the samples were measured and the imaginary part which arise from the change in absorption is found to be dominant.
