A twin-rib wa¨eguide optical switch is designed by the discrete spectral index method. An optimized rib height achie¨es a crosstalk le¨el of less than y40 dB with a coupling length characteristic that is weakly dependent on the rib separation, hence pro¨iding a larger error margin in fabricating the
The scope of the spectral index method for solving general planar waveguiding problems is analysed by first showing how simple it is to set up a closed-form transcendental equation whose solution is very accurate; the solution is so fast that the method can be used as a subroutine, making it possibl
