Abstract :
We demonstrate coupled spiral-shaped microdisk resonators with asymmetric non-evanescent coupling between the two microdisks in silicon nitride. Initial experiments reveal reciprocal throughput-port transmissions with high-Q. Simulations show input-direction-dependent drop-port transmissions and asymmetric mode-field distributions.
