Abstract: PURPOSE:To provide a miniaturized and light in weight optical transmitter with high reliability in which high speed scanning and tracking are attained. CONSTITUTION:An optical waveguide 3, an optical magnification section 4, and a flat optical waveguide 5 are formed in a dielectric 2 made of an LiNbO 3 or the like.

Then a 1st phase shift section 6 corrects unmatching of the phases generated by the optical magnification section 4 and a 2nd phase shift section 7 provides a linear phase gradient to an output wave front of the optical wave. The optical beam outputted from an output wave front is directed in an optional direction in two-dimension or three-dimension by varying the phase gradient optionally provided by the 2nd phase shift section 7. Since the phase gradient required for beam scanning is set by using the electrooptic effect, high speed control is attained for beam scanning and tracking.
