Tunable and reconfigurable microwave filter by use of a Bragg-grating-based acousto-optic superlattice modulator

This is the authors' abstract. We don't add key points for this paper.

We present an all-optical novel configuration for implementing multitap transversal filters by use of a broadband source sliced by fiber Bragg grating arrays generated by propagating an acoustic wave along a strong uniform fiber Bragg grating. The tunability and reconfigurability of the microwave filter are demonstrated.
