Abstract
An optical scanning device for deflecting a plurality of light beams is disclosed. The device includes a plurality of deflection means for deflecting each of the plurality of light beams. The means are formed in a thin film waveguide, and distributes a refractive index of the waveguide by an electro-optic effect according to input signals to cause diffraction due to the distributed refractive index, thereby deflecting a plurality of light beams.
