ABSTRACT:
An electro optic device includes an optical element in which a refractive index distribution, changes according to the intensity of an electric field generated therein such that an incident laser beam is scanned. First and second electrodes are provided on two opposite surfaces of the optical element. A distance between electrodes of the first and second electrodes of the optical element decreases continuously or in a stepwise manner from an emission end surface toward an incident end surface.
