We investigate the local field enhancement properties of a 2D nano-cavity by using finite-difference time-domain (FDTD) method. The 2D nano-cavity is built by two pieces of silver slabs with periodical subwavelength corrugations on their inner boundaries. Numerical simulation result shows that the 2D nano-cavity can confine and enhance light field within the region smaller than the diffraction limit in a relatively broad range of wavelength. The result is useful for the research and development of new kinds of broadband optical sources used in WDM optical communication networks or micro-optical sensor system.
