Abstract: (1669 Views)
In the present work, the nonlinear refractive index of silver nanowires (Ag NWs) doped with PVP polymer films is determined using z-scan technique. This work was particularly done utilizing a close aperture placed in front of the detector to show the effect of the Ag NWs on the nonlinear refractive index of the PVP films. It’s found experimentally that the nonlinear refractive index of the films can be varied by changing the compositional percentage of Ag NWs in PVP films. The obtained nonlinear refractive index of the samples indicated that Ag NWs can act as a good material for controlling the third order nonlinear coefficient in gain media due to its large nonlinear optical properties.
