摘要：

We employ the Threedimensional split-step fast Fourier transform beam propagation method to demonstrate that losses associated with a strongly-guiding semiconductor rib waveguide Y-junction can be substantially reduced by adding an optimized length of an initial straight broad waveguide segment. In addition, we show that the resulting transmission is relatively insensitive to the exact waveguide dimensions and in particular to the geometry of the Y-junction vertex. © 1990 IEEE
