✦ Synopsis

Perfectly matched anisotropic absorbers are introduced in two-and three-dimensional beam propagation methods. The anisotropic perfectly matched layer does not require the modification of Maxwell's equations, and can be easily implemented in codes which deal with anisotropic materials. Finite-element semi¨ectorial and full-¨ectorial formulations ha¨e been considered to pro¨e the efficiency of the proposed approach.

The perfectly matched layer boundary condition is incorporated into the beam propagation method based on a "nite element scheme for 3-D optical waveguides. Not only an approximate scalar formulation but a full-wave formulation is presented. Its e!ectiveness is veri"ed by way of numerical examples.
