Abstract
An optical coupling structure includes a light source that emits light; and an optical waveguide that has on a given end, a mirror surface that reflects the light emitted from the light source, the optical waveguide guiding the light reflected by the mirror surface to another end. In the optical coupling structure, a traveling direction of the light emitted from the light source is inclined toward the given end of the optical waveguide and is, with respect to a normal line of the mirror surface, at an angle that is greater than 45 degrees and that satisfies a condition for complete reflection of light on the mirror surface and a condition for complete reflection of light in the optical waveguide.
