Paper Abstract

In the theoretical modeling of the performance of optical directional couplers with nonuniform waveguide spacing, coupled-mode equations involving varying coupling coefficients are often solved numerically. We show that, when the waveguides are dissimilar, direct numerical integration of the equations may result in variation of the total power along the coupling direction. A modification of the numerical scheme is proposed to make the numerical calculation satisfy power conservation, as is required in modeling a realistic coupler with very low insertion loss.
