Abstract
Optical dispersion compensation devices are provided herein that are based on one or more optical ring resonators. The degree of dispersion compensation can be selected by controlling the degree of under-coupling and by tuning physical properties of the optical ring resonators. In a first implementation, an optical ring resonator under-coupled to an optical throughput bus can be used to provide positive or negative dispersion compensation depending on tuning of the optical ring resonator, which widens the dispersion window. In a second implementation, an over-coupled optical ring resonator can be added to the optical throughput bus to provide a cascaded filter. In a third implementation optical ring resonators arranged in series between an optical input bus and an optical output bus can be used to both tune dispersion compensation and provide demultiplexing.
