Abstract:
1. A tunable Radio Frequency (RF) filter device comprising: a tunable optical source configured to generate an optical carrier signal; a modulator coupled to said tunable optical source and configured to modulate the optical carrier signal with an RF input signal; first and second optical waveguide paths coupled to said modulator and having first and second dispersion slopes of opposite sign from each other; at least one of said first and second optical waveguide paths comprising at least one optical splitter and combiner pair therein; and an optical-to-electrical converter coupled to said first and second optical waveguide paths and configured to generate an RF output signal with at least one frequency notch therein based upon said tunable optical source and the first and second dispersion slopes of opposite sign from each other.
