Abstract:
1. An optical waveguide comprising: an optical waveguide body having a core portion and a cladding portion; a first optical wiring connected to an end portion of the core portion of the optical waveguide body; a second optical wiring connected to an opposite end portion of the core portion of the optical waveguide body; a first device configured to pull the end portion of the core portion of the optical waveguide body; and a second device configured to pull the opposite end portion of the core portion of the optical waveguide body, wherein the first optical wiring is placed on the first device and the second optical wiring is placed on the second device such that the end portions of the core portion are pulled and a tensile stress is applied and maintained on the core portion of the optical waveguide body, and the first device and the second device are configured to pull the core portion of the optical waveguide body such that the end portions of the core portion are pulled in a direction substantially equal to and a direction opposite to a progress direction of a transmitted light in the optical waveguide body.
