Abstract

Here, we address the need for fast computation of subwavelength structures. It allows fast conception of optical devices. We present a modal method based on B-splines formulation which solves Maxwell equations. The two assets of this method are to use non uniform B-splines permitting to adapt the mesh to the structure, and to produce sparse matrices which permit to speed up the computation. As an illustration, we make use of this method for the design and analysis of variously shaped infrared optical devices.
