| 摘要 |
A filter apparatus is described that includes an electrical input signal, an optical source, an optical modulator, first and second pluralities of photonic delay lines, an optical switch, a combiner, and a photodetector. The optical modulator is coupled to the electrical input signal and the optical source. The first plurality of photonic delay lines are coupled to the optical modulator. The optical switch is coupled to the optical switch. The combiner combines the outputs of the second plurality of photonic delay lines to provide a combined output. The photodetector is coupled to the combined output of the combiner to provide a first filtered output of the electrical input signal.
