Paper Abstract

Optical limiting is an essential concept for nonlinear optics and its applications. Recently, the nonlinear response in a two-dimensional (2D) superlattice (a periodic structure with its refractive index modulated in two dimensions) was studied for its potential applications in new optical devices. The available results are only related to the transition between a low transmission state and a high transmission state in the allowed bands. Up to date, optical limiting is not explored in 2D case with one incident wave. In this paper, a novel structure, which is composed of two dissimilar superlattices, is proposed for the optical limiting. The novel structure is named hetero- superlattice-junction structure in this paper. In terms of real-space-matching concept, optical limiting is demonstrated in a 2D nonlinear hetero-superlattice-junction structure, while this phenomena is proved unavailable in a 2D nonlinear superlattice.
