ABSTRACT:
A single-type array optical conversion apparatus includes a substrate and an optical waveguide. The substrate has a rectangular area sandwiched by first and second end faces opposing each other. The optical waveguide is formed in the rectangular area and has a single input waveguide exposed on the first end face of the rectangular area, and a plurality of branched waveguides exposed on the second end face of the rectangular area. The optical waveguide is branched into 2.sup.n by repeating branching into two waveguides from the first to second end face of the rectangular area. The input waveguide is optically connected to a single-type optical fiber, and the branched optical waveguides are optically connected to a multi-type array optical fiber.
