Abstract
We present the optical Kerr effect, and nonlinear optical absorption studies of two closely spaced distributions of silver nanoparticles embedded in silica containing ion-implanted silicon nanocrystals. The z-scan technique was used to explore the third-order optical nonlinear response at 830 nm with 80 fs pulses. Two-wave mixing experiments were comparatively examined by a vectorial method at 532 nm wavelength using nanosecond pulses. The femtosecond results reveal that both saturated and two-photon absorption seem to contribute to the nonlinear absorption observed. From nanosecond observations, we identify that a remarkable enhancement in the third-order optical nonlinearity is achieved by the double-implantation process.
