Abstract :
A notch filter acoustically induced in a 1 cm long chirped fiber Bragg grating is experimentally investigated. The notch reflectivity (2.5 dB - 25 dB) and bandwidth (9 nm - 3 nm) are tuned by an electrical signal. The reduction of the grating and modulator size for achieving the acousto-optic modulation compared to previous works, points out for more efficient acousto-optic devices in standard optical fibers.
