The effects of cascading the ring resonator to form wavelength filters is a major focus of this paper, the results tested between the two methods of cascading the rings are the trends between the two types of cascaded rings for the ON-OFF ratio where the serially cascaded method was found to make better filters, -3dB bandwidth which is the width of the pass-band of through-port and drop-port where both the two cascading methods have the same effect as the numbers of rings increases. The delay times of the output for use in telecommunication are also simulated illustrating that only the parallel cascaded method provides this property.
