摘要： An optical waveguide is formed on a ferroelectric substrate having a thickness of 20 μm or less by diffusion of a dopant or ion exchange. The optical waveguide has a non-branched section 2a operating on single mode and a pair of branched sections branched from the non-branched section 2a. Each of the branched sections has a connecting part 7 extending from a branching end 10 and a multi mode propagating part 8 continuously formed from the connecting part 7. The multi mode propagating part 8 has a width “m” larger than a width “t” of the non-branched section. A width “p” of the connecting part increases from the non-branched section 2a toward the multi mode propagating part 8.
