Design Consideration Analysis of Optical Filters Based on Multiple Ring Resonator
Imran Khan
Optical filters are the devices for channel adding or dropping in optical fiber based communication system. This paper described a simulation based design analysis on optical filters using multiple ring resonators. The ASPIC (a frequency-domain photonic circuit simulation tool) is used through the whole analysis. It is found that by using multiple rings and vernier effect it is possible to design narrow band optical filter. 10th order or even more ordered filter can be designed by using multiple ring resonators. If the number of rings is increased then the steepness of the filter response will also increase within certain limit.
