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.

摘要： A first optical device has an optical fiber mount with an optical fiber disposed thereon, and an optical demultiplexer for demultiplexing a portion of an optical signal beam transmitted through the optical fiber, as a demultiplexed optical signal beam, and guiding the demultiplexed optical signal beam out of the optical fiber. The optical fiber has a first tapered surface for emitting the demultiplexed optical signal beam therethrough. The first tapered surface is inclined at an angle θ1 of at least 1° to an optical axis of the optical fiber. The distance (h) between the optical axis of the optical fiber and the first tapered surface is progressively greater along the direction in which the optical signal beam travels through the optical fiber.
