Tunable RF filter device using optical waveguide paths with splitter and combiner pairs and related methods |
摘要 |
A tunable Radio Frequency (RF) filter device includes a tunable optical source generating an optical carrier signal, and a modulator coupled to the tunable optical source and modulating the optical carrier signal with an RF input signal. The tunable RF filter device may include first and second optical waveguide paths coupled to the modulator and having first and second dispersion slopes of opposite sign from each other, one or more of the first and second optical waveguide paths comprising an optical splitter and combiner pair therein, and an optical-to-electrical converter coupled to the first and second optical waveguide paths and generating an RF output signal with a frequency notch therein based upon the tunable optical source. |

1. A method of Radio Frequency (RF) filtering comprising:
generating an optical carrier signal using a tunable optical source; modulating the optical carrier signal with an RF input signal using a modulator coupled to the tunable optical source and first and second optical waveguide paths coupled to the modulator and having first and second dispersion slopes of opposite sign from each other, at least one of the first and second optical waveguide paths comprising at least one optical splitter and combiner pair therein; and generating an RF output signal with at least one frequency notch therein based upon the tunable optical source using an optical-to-electrical converter coupled to the first and second optical waveguide paths and based upon the first and second dispersion slopes being of opposite sign from each other. |
