Abstract
An optical waveguide module-mounted device that includes an optical waveguide module in a separation type case. The module includes an optical waveguide chip and a pair of optical fibers connected to the optical waveguide chip. The fibers are connected such that the optical axes of the chip and the fibers are aligned with each other. The separation type case has an optical-fiber lead-in portion and an optical-fiber lead-in groove. The optical-fiber lead-in portion has an optical-fiber open groove at open portion of the separation type case. The optical-fiber open groove leads the optical fiber out of the separation type case. The optical-fiber lead-in groove positions the optical fiber and is connected to the inner end of the open groove. The optical-fiber open groove is deeper than the optical-fiber lead-in groove.
