-Application of high-Q microresonators as integrated optical filters

One of the most improtant applicaiton of high-Q circular resoantors is in the design and fabricaiton of compact high-Q optical
filters. We have studied the importance of the quality factor as well as fabrication issues associated withthis important class of optical filters.
