A device and method involving a plurality of lasers for generating and modulating a tunable, high-frequency signal for a wireless communication system, including an optical waveguide, may be produced using standard components of optical communication technology. A signal source may be provided which generates an optical signal and is disposed on one side of the optical waveguide. At least one means is provided for generating harmonic waves of this signal, which propagate as frequency mix in the optical waveguide. Two pump lasers are provided for the injection of pump waves on an opposite side of the optical waveguide, which are adapted so that together they amplify two harmonic waves of the frequency mix by stimulated Brillouin scattering. The rest of the harmonic waves are attenuated by damping in the optical waveguide. The two amplified harmonic waves are superposed in a photo element in heterodyne fashion and generate the RF signal. |
