ABSTRACT:
An acousto-optical waveguide device for the wavelength selection of an optical signal comprises two polarization conversion stages, one polarization selective input element, one polarization selective output element and two intermediate polarization selective elements located at the output of the first conversion stage and at the input of the second conversion stage, respectively; the intermediate polarization selective elements have two branches connected together and two branches not connected together located on opposite sides with respect to the branches connected together.
