The third order nonlinear optical properties of TPP incorporated PMMA thin films were probed by means of z-scan technique. The thin films of the order 200-400 nm were fabricated using spin-coating technique. The UV-Visible absorption spectrum shows no variation in the absorption wavelength region with the increase of TPP concentration in PMMA matrix. The developed composite thin films exhibit strong nonlinear absorption (NLA) and nonlinear refraction (NLR) coefficients (β and n2) in the range 10−6 to 10−5 m/W and 10−13 to 10−12 m2/W respectively. The measured third order nonlinear susceptibility, χ(3) of composite thin films was found to increase with the TPP concentration. The obtained results indicate that the developed spin coated thin films are potential candidates for nonlinear optical device fabrication. |
