Abstract
We report a methodical study about the third order optical nonlinearity of anisotropic growth of ZnO crystals embedded in polymeric matrices and nanowires on the glass substrate with the use of pre-existing textured ZnO, ZnS and TiO2 seeds using a Z-scan method with Nd:YAG laser (532Â nm, 7Â ns, 10Â Hz). The studies show that the optical nonlinearity of ZnO crystals is highly dependent on the structural geometry and the correlation of semiconductor. Our study offers better insights into the third-order nonlinear optical characteristics of ZnO crystals and reveals great potential for applications in nonlinear photonic devices.
