ABSTRACT:
Light beams emitted from a semiconductor laser are introduced into an optical guide. The light beams linearly passing inside the optical guide are radiated one after another in the direction substantially perpendicular to the passing direction so as to be received by an optical modulator disposed on the optical guide over the length thereof, where the light beams are selectively modulated and then radiated out throughout the length thereof.
