Sidelobe suppression in all-fiber acousto-optic tunable filter using torsional acoustic wave
We propose two techniques to suppress intrinsic sidelobe spectra in all-fiber acousto-optic tunable filter using torsional acoustic wave. The techniques are based on either double-pass filter configuration or axial tailoring of mode coupling strength along an acousto-optic interaction region in a hi...
