Single crystal Al2O3 substrates have been implanted with 160-keV Au+ to a dose of 0.6 × 1017 or 1.0 × 1017 cm−2, with a postimplantation annealing for 1 h at 800°C in air. The obtained composite layers were studied by the method of linear optical reflection; the nonlinear optical characteristics were determined by the RZ-scan technique using picosecond radiation pulses of an Nd:YAG laser operating at 1064 nm. The appearance of a characteristic surface optical plasmon resonance band in the… Expand

Ultrafast optical phase modulation with metallic nanoparticles in ion-implanted bilayer silica.
Control of the optical phase is controlled by an ultrafast all-optical phase modulator device by using a combination of two different metallic ion-implanted silica samples, as a consequence of a significant optical Kerr effect present in these nanocomposites. Expand
