摘要：
An optical cavity includes a ring defining an internal boundary and an external boundary, at least one of which is periodically modulated to define a gear-shaped configuration including a plurality of teeth, thereby enabling a plurality of slow-light modes. At least one physical defect may be defined within the periodically modulated internal boundary and/or external boundary to thereby enable at least one localized mode. At least one waveguide is coupled to the ring.
