  • Patent number: 5784509
    Abstract: The invention provides an improved simplified waveguide-optical fiber connection structure for connecting a waveguide and an optical fiber. The waveguide-optical fiber connection structure comprises an optical fiber, a waveguide substrate having a waveguide integrally formed thereon and having a first guide groove formed thereon adjacent an end portion of the waveguide for positioning the optical fiber therein, and a fiber substrate provided in an opposing relationship to the first guide groove for cooperating with the first guide groove to hold the optical fiber thereon. The waveguide-optical fiber connection structure can be applied to a waveguide circuit which is employed for optical communication, optical information management and so forth.
