Abstract
Propagation constant errors (PCEs) of guided modes in regions of multimode interference in optical networks were analyzed. Results show that a graded-index waveguide can effectively decrease the PCEs. An example based on an exponential function is presented. Numerical results show that addition of a graded-index waveguide greatly improves device performance in this structure.
