Abstract: A device and method for tuning a ring resonator using self-heating stabilization is provided. A light source is controlled to produce an optical signal, input to an optical ring resonator, at a power where self-heating shifts a resonance wavelength of the optical ring resonator by at least 10 picometers, the self-heating comprising absorption in the optical ring resonator of optical power from a received optical signal. Prior to using the optical ring resonator at least one of modulate and filter the optical signal at the optical ring resonator, a heater of the optical ring resonator is controlled to an operating temperature at which the resonance wavelength of the optical ring resonator is greater than a respective wavelength of the optical signal.

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.
