Fan-in/fan-out device and optical communication apparatus

Abstract

A fan-in/fan-out device includes single-core fibers and a waveguide member including waveguides that are each optically coupled to a core of a corresponding one of the single-core fibers, and connect to an optical communication member. A distance between adjacent waveguides of the waveguides on a side of the single-core fibers is equal to or greater than a distance between adjacent waveguides of the waveguides on a side opposite to the single-core fibers. An optical characteristic of a first coupling waveguide including the core of a first single-core fiber of the single-core fibers and the waveguide coupled to the core of the first single-core fiber is different from an optical characteristic of a second coupling waveguide including the core of a second single-core fiber of the single-core fibers and the waveguide coupled to the core of the second single-core fiber.
