Abstract :
The effects of structure parameters on the bend loss of rib silicon-on-insulator (SOI) bend waveguides have been analyzed by means of the effective index method (EIM) and 2D bend loss formula. The simulation results indicate that the bend loss decreases with an increase of bend radius and waveguide width, as well as with a decrease of the step factor of the rib waveguide. Moreover, the optimal structure parameters have been found when the bend waveguides are single-mode.
