  • Abstract
    Large and ultrafast cubic optical nonlinearities in thin films containing poly (methyl methacrylate) (PMMA)-TiO2 nanocomposites were observed using 780-nm, 250-fs laser pulses. The recovery times of the nonlinearities were found to be ∼1.5 ps. The best figures of merit were obtained in one of the films prepared with a 60% weight percentage of titanium isopropoxide. These findings strongly suggest a potential application of PMMA-TiO2 nanocomposites for all-optical switching devices.
