Abstract :
Performance of a serially coupled integrated optic triple ring resonator (TRR) which can be used as an optical filter has been investigated in this article. Delay line signal processing and Mason´s rule have been used to analyze the TRR architecture. The simple architecture is capable of providing an efficacious free spectral range (FSR) of 1050 GHz. So far this is the widest reported FSR for the similar class of ring resonator. Two important phenomena in the form of group delay and dispersion have also been discussed in this article.
