The application of the acoustic-induced vibration on a fiber Bragg grating has been proposed as the function of controlling reflectivity levels and switching reflection wavelengths. Moreover, a switchable multi-wavelength optical filter is expected to develop for various applications in optics. Thus an acousto-optic interaction in a superstructure fiber grating (SFG) can provide a multi-wavelength reflective filter with the function of switching the operation wavelength. In this paper, we experimentally demonstrated that the channels of a blazed SFG could be increased or switched as the acoustic waves were launched into the fiber. When the acoustic wave is applied in the fiber and travels along the fiber axis, the cladding modes of a blazed SFG can couple back to the core mode by acousto-optic interaction in the fiber. The grating reflectivity and the number of the induced wavelength channels can be controlled by acoustic flexural amplitude. Thus, this device acts as a switchable multi-wavelength comb filter for the applications in a WDM system, or in fiber lasers or in fiber sensors.
