All-fibre acousto-optic filter with low polarization sensitivity and no frequency shift
An acousto-optic tunable filter based on an all-fiber null coupler, exhibiting low polarization sensitivity and zero net frequency shift, is demonstrated. The polarization dependence has been eliminated by simultaneously applying two acoustic waves that independently satisfy the phase-matching condi...
