Abstract

A new photonics-based approach for interference mitigation utilizing the nonlinear response of optical modulators is described. The technique is analyzed both theoretically and experimentally with excellent agreement. Proof-of-concept experiments demonstrate upward of 78-dB suppression of a large interfering signal, while degrading the response to small signals of interest by only 8 dB.
