Patent ID: 8100589

Claim:
An optical module comprising: an optical waveguide including a waveguide core through which light propagates, and a clad configured to trap the light in the waveguide core; and a circuit board on which a surface-type optical element is mounted, wherein the optical waveguide further includes: a reflective surface from which an end face of the waveguide core is exposed, the reflective surface being provided on an inclined face at one end face of the optical waveguide in an extending direction of the waveguide core; an opposing pair of waveguide support portions integrally formed with the clad and disposed apart from one another, each one of the pair of waveguide support portions having an inner waveguide support wall such that the inner waveguide support walls face each other; and an element mount opening formed into the clad such as to be opposite from the reflective surface, the element mount opening having a size such as to contain the optical element, wherein the optical waveguide is mounted on the circuit board while the optical element is contained in the element mount opening and is aligned with the reflective surface of the optical waveguide and wherein the element mount opening is defined by the inner waveguide support walls of the opposing pair of waveguide support portions, a light incident/exit surface of the clad spanning the inner waveguide support walls through which light perpendicularly enters thereinto or perpendicularly propagates therefrom and a rear surface of the clad spanning the inner waveguide support walls and extending perpendicularly from the light incident/exit surface.
