Abstract
We report the acousto-optic induced multiband reflection in sinc-sampled fiber gratings, in which the induced-wavelength-channels at both sides of each existing channel can be switched by applying an acoustic wave propagating along the fiber. This novel comb filter can redirect a large number of wavelength channels at the same time in a wavelength division multiplexing (WDM) system and will offer a new functionality in the evolution of the current WDM network toward a more complex future system with automated routing functions.
