Paper Abstract

The device studied here consists of a corrugated waveguide filled with a nonlinear dielectric (ZnS), and bounded by a metal (silver) on one of its sides. We concentrate on the second harmonic signal produced when a high energy laser beam impinges the device, and we try to enhance the signal intensity through the resonant excitation of a guided mode. Indeed, it has been established [1] that this electromagnetic resonance is a good candidate to increase the local field and, thus the sources for various nonlinear effects [2, 3]. It is shown that a convenient optimization of the grating groove depth can lead for signal enhancements as high as 105, compared to a nonlinear slab.
