Abstract

PURPOSE:To simplify the production of the titled element, to miniaturize the structure and to omit reguration by forming plural straight optical waveguides on an optical waveguide forming member so as to be intersected with each other and constituting the system so that the ray of light incident upon a waveguide is distributed into other waveguide at a prescribed ratio. CONSTITUTION:Straight optical waveguides 1, 2 with 10mum width are formed on an optical waveguide forming member at the intersecting angle of phi. The ray of light incident upon an optical waveguide 1 as shown by an arrow is distributed into respective waveguides 1, 2 at an intersecting part 3. The distribution ratio is optionally determined by appropriately selecting the density of Ti or the like forming the optical waveguides by diffusing it on a substrate such as LiNbO3 and quartz and the intersecting angle phi. Since lenses, mirrors, etc. are not required for the element, the production is simplified, the element is miniaturized and its reguration is made unnecessary.
