1. A ring cavity device, comprising:
a passive ring waveguide with a plurality of regions;
a plurality of separate active waveguide structures vertically coupled to the passive ring waveguide, each active waveguide structure being coupled to one region of the passive ring waveguide, two regions coupled to the plurality of separate active waveguide structures being separated from each other; and
at least one input/output waveguide horizontally coupled to the passive ring waveguide, and the plurality of separate active waveguide structure providing a gain to the passive ring waveguide to compensate loss.
