Patent ID: 8052337

Claim:
An optical module comprising: an optical element for transmitting or receiving an optical signal, an optical waveguide having a core part made of a material with translucency and a clad part made of a material having an index of refraction different from an index of refraction of the core part for optically coupling with the optical element and transmitting the optical signal, and a package for accommodating at least one end of the optical waveguide including an entrance/exit port of the optical signal and the optical element; wherein the package is formed to a concave shape by side walls rising from a bottom plate mounted with the optical element; wherein a surface of said end of the optical waveguide facing the bottom plate is configured by a first region including the entrance/exit port and a second region different from the first region; wherein the second region is the region of the optical waveguide that is supported by a first side wall as one of the side walls rising from the bottom plate; wherein the package includes a supporting part; wherein the supporting part comprises: the first side wall supporting one part of at least two sides of the second region traversing the optical waveguide in the package; and a second side wall as another one of the side walls supporting one part of at least a side of the first region in a direction different from the first side wall; and wherein the supporting part is a member which shields light.
