Abstract:
A planar packaged optical module comprising:a housing; a substrate provided within the housing; a conversion device provided in the housing, the conversion device being operable for converting one of an electric signal and an optical signal substantially into the other; an optical fiber connected to the housing with a retaining member, the retaining member being adhered to the housing by a first adhesive, and the optical fiber being adhered to the retaining member by a second adhesive, the optical fiber being fixed to the substrate such that an end surface of the optical fiber opposes the conversion device, wherein the first adhesive is made of a first resin having an intrinsic glass-transition temperature, and the second adhesive is made of a second resin having an intrinsic glass-transition temperature greater than the glass-transition temperature of the first resin.
