ABSTRACT
Ordered Au nanoparticle arrays were fabricated on fused quartz substrates using nanosphere lithography. Linear and nonlinear optical properties of triangular Au nanoparticle arrays were investigated. Two LSPR peaks due to the surface plasmon resonance of Au particles were observed. The nonlinear optical properties were measured using the Z-scan technique at a wavelength of 532 nm and pulse duration of 10 ns. The nanoparticle arrays exhibit distinct nonlinear absorption saturation behavior, the absorption coefficient was determined to be -3.5 × 103 (cm/GW).
