A wavelength-switchable fiber ring laser that includes a Bragg grating-based acousto-optic modulator is reported. When a longitudinal acoustic wave propagates along a fiber grating, it modulates periodically the effective period, which causes that additional bands of reflection appear on both sides of the Bragg wavelength. Wavelength switching of the laser emission is achieved by dynamic adjust of the peak reflectivity of the different bands.
