We demonstrate an acousto-optic tunable filter based on a two-mode elliptical-core fiber. The filter is operated at 1090 nm as a broadband notch filter used for spectral flattening and as a bandpass filter with subnanometer bandwidth. When used for spectral flattening the FWHM bandwidth is optimized
