Abstract EN
Finite difference beam propagation method is an accurate numerical procedure, used here to explore the switching dynamics of a nonlinear coherent directional coupler.
The coupling lengths derived from this simulation are compared with coupled mode theories.
BPM results for the critical power follow the trend of the coupled mode theories, but it lies in between two coupled mode theories.
Coupled mode theory is sensitive to numerical approximations whereas BPM results practically do not depend on grid size and longitudinal step size.
Effect of coupling-region-width and core-width variations on critical power and coupling length is studied using BPM to look at the aspects of optical power-switch design.
