    An optical beam scanner integrated with two phased array waveguides is fabricated. The optical beam scanner consists of twin GaAlAs/GaAs waveguides which are integrated with an optical branch for optical power distribution to the twin waveguides. The optical beam can be deflected about 1.0 degree by applying a reverse bias of 10 V to the pn junction in one of the waveguides.
