<P>PROBLEM TO BE SOLVED: To provide an optical wave guide device that efficiently guides and discharges unnecessary light to the outside of a substrate or a whole of the optical wave guide even when the optical wave guide is integrated. <P>SOLUTION: An optical wave guide 2 is formed on the substrate 1, and the optical wave guide is composed of main optical wave guides (21 to 23) for propagating signal light, and optical wave guides (31 to 33) for the unnecessary light that remove the unnecessary light from the main optical wave guide. At an intersection where the optical wave guides for the unnecessary light and the main optical wave guides cross, the optical wave guides (32 to 33) for the unnecessary light are segmented while sandwiching the main optical wave guides. <P>COPYRIGHT: (C)2012,JPO&INPIT |
