Abstract

An acoustooptic tunable filter based on an all-fiber null coupler, exhibiting low polarization sensitivity and zero net frequency shift, isdemonstrated, The polarization dependence has been eliminated by simultaneously applying two acoustic waves that independently satisfy the phase-matching condition for the two eigenpolarization states, A simple double-pass arrangement is employed to exactly cancel the net frequency shift and to provide an enhanced spectral sidelobe suppression of better than -17 dB.
