Abstract

The beam propagation method (BPM) used for the design of an integrated optical (IO) coupler was proposed in this paper. A modal of the IO coupler was set up in BeamPROP software that is based on the BPM, and then the modes and the bi-directional propagation in the proposed coupler were investigated. Finally, the structure and dimension of the coupler was determined.
