Abstract:
An optical modulation element comprising:an electro-optic crystal substrate including individual electrodes arrayed and formed one-dimensionally on one surface of the substrate and also including a common electrode formed on the other surface in opposition to said plurality of individual electrodes;wherein each portion of said electrode-optic crystal substrate, interposed between said common electrode and each said individual electrode, constitutes an aperture portion, the aperture portion being switched between a light-transmitting state and a light cut-off state by controlling voltage between said opposite electrodes, and light incident on said aperture portion in a direction perpendicular to the arrayed direction of said individual electrodes from one surface of said electro-optic crystal substrate being modulated; andwherein each said individual electrode is formed into a shape which partially shares adjacent individual electrodes with a region on said electro-optic crystal substrate in the arrayed direction of said individual electrodes which is occupied by each said individual electrode.
