摘要
A technique for implementing a tunable micro-ring filter is disclosed. According to an embodiment of the present invention, a tunable filter for optical communication systems comprises a first waveguide forming a pattern with a second waveguide; a resonator coupled to the first waveguide and the second waveguide wherein the resonator comprises a nonlinear optical material; an electrode structure sandwiching the first waveguide, the second waveguide and the resonator; the electrode structure adapted for receiving a tuning signal and tuning an effective index of the resonator in response to the tuning signal; and a substrate supporting the first waveguide, the second waveguide, the resonator and the electrode structure.
