ABSTRACT:
An optical waveguide has a multiple tilted surface acoustic wave transducer array for diffracting a wide light beam propagating through the waveguide. Adjacent transducers are relatively positioned so that at the crossover frequency, the light beams diffracted from the transducers are added in phase.
