Theoretical simulation on SHG in broad wavelength range using ZnO nanorods

Abstract

In present work, we have done detail theoretical simulation studies in broad wavelength range of 800 nm to 4000 nm for SHG with ZnO nanorods. The Fresnel transmission factors for fundamental and SHG radiation can affect the SHG process. So the variation of these parameters was studied within the aforementioned wavelength range. These transmission factors were found to be in the range of 0.661–0.674 and 1.66–1.75 for fundamental and SHG radiation respectively. Refractive indices also control the behaviour of SHG process. So detail investigation on it is also done for the entire wavelength range of 800 nm-4000 nm by taking the Sellmier’s Equation. Effect of these aforementioned parameters on efficiency of the second harmonic generation process is also studied.
