We propose and demonstrate a novel apodization technique for an elliptical-core two-mode fiber acousto-optic filter by twisting the fiber and adjusting the acoustic polarization. The sidelobe suppression in the filter spectrum was improved from 9.7 to 15.5 dB . A theoretical analysis that includes acoustic birefringence explains the experimental results with good agreement.
