Abstract
A multi-channel dispersion compensator comprising an optical signal waveguide that forms an input end for receiving an optical signal and an output end for providing a filtered optical signal. The multi-channel dispersion compensator also includes a series of closed-loop resonators providing frequency delay to at least one channel of the optical signal. The optical signal waveguide and each closed-loop resonator form a tunable coupler having a coupling value. The coupling value for each tunable coupler is selected to minimize constant dispersion and linear slope dispersion of the optical signal. Methods of fabrication and use are also described.
