Abstract:
The generation of two-dimensional surface plasmon interference patterns using a three-dimensional dielectric diffraction grating with a metal film is studied. It is shown that high contrast interference patterns with a period several times smaller than the wavelength of the incident light can be produced. At the interference maxima, the field intensity is tens times than that of the incident wave. Techniques to control the interference pattern period and configuration by varying the wavelength and the polarization of the wave are discussed.

Key words:
diffraction, diffraction grating, photolithography, interference pattern, surface plasmon.
