Abstract

Embedding nonlinear media in the slit region of metallic nano-optic lens is proposed as a new method of active modulating the output beam. Two important phenomena, beam deflection and focusing, have been studied in detail. A developed Finite Difference Time Domain (FDTD) method has been performed to account for the nonlinear response. The simulated results show that the deflection angle and focus length can be controlled easily by the intensity of incident light in the structures. The physical principle of the phenomena is explained by the Surface Plasmons (SPs) excitation and Fabry-Pérot (F-P) resonance in the nanoslit.

(a) Schematic view of the three-slit structure under study. The parameters are as follows: the thickness of the Ag film is 560nm, the distance between two silts is 400nm(center to center), the slit width is 90, 70, and 60 nm in sequence from up to down, the deflection angle of the output beam is denoted as θ. A TM-polarized plane wave (850 nm wavelength) is incident from the left side of the slit array. The FDTD simulations of electric-field intensity |E| 2 distribution are shown at different incident amplitudes: (b) E0 =1×108V/m and (c) E0 =2.5×108V/m.
