There is a great potential of microring-resonators as optical add/drop-multiplex modules in photonics with very large scale integration. The area consumption per ring is incredibly small, and complex circuitry seems feasible. But, enroute to application the production of ring resonators has to ensure specifications which can compete with those of other frequency periodic/selective devices. This ultimatley leads to tight fabrication tolerances, and polarisation dependence and insertion loss of an unit enter the assessment as well. Capabilities to manufacture microring-resonator devices with different materials and technologies are valuated in this context.
