Abstract
An acoustooptical wavelength device for wavelength selection includes one substrate of a birefringent and photoelastic material on which there is formed: first and second rotation stages of the polarization plane of an optical signal in a first wavelength interval, wherein each stage comprises at least one optical waveguide traveled over by the signal; at least one optical waveguide, connecting the two stages and carrying one single polarizer consisting of an evanescent-wave polarization coupler; and at least one optical waveguide carrying one polarizer being finally provided downstream of the second stage.
