Abstract :
Coupled-optical-microcavity geometries incorporating non-adjacent-cavity coupling and "negative" ("inductive") coupling are proposed. These enable new compact, quasi-elliptic microring filters, and can circumvent Kramers-Kronig causality constraints to support square- amplitude and linear-phase response over >80% of the passband.
