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 …

Fiber-based acousto-optic devices have been demonstrated in several configurations for
their uses in switches, modulators, and frequency shifters, 1 as well as in tunable filters. 2 …

All-fiber acousto-optic devices based on the null fused taper coupler have been successfully
demonstrated as frequency shifters, variable splitters, switches and tunable filters. In this …

We demonstrate an optical filter that utilizes acousto-optic coupling between the spatial
modes that propagate in a two-mode elliptical-core fiber. The optical bandwidth at 1090 nm …
