We report an all-fiber acousto-optic tunable filter based on a two-mode photonic crystal fiber. The properties of photonic crystal fiber allow us to demonstrate a notch filter tunable from below 700 to 1700 nm with a single acoustic transducer. The extreme dynamic range coupled with small insertion loss and fast response time (∼100 μs) makes this device promising for ultrawideband optical systems.
