ABSTRACT:
This invention relates to an optical module for coupling an optically operative device with an optical fiber. Near the optically operative device, the module includes a fiber saddle on which the optical fiber is affixed by soldering to optically connect the operative device and the fiber. The fiber saddle is provided on a heat insulative substrate, which also mounts the optically operative device, so that heat for melting the solder will not be conducted through the fiber saddle when the optical fiber is soldered to the saddle. Thus, the temperature necessary for soldering can be attained rapidly. A mounting surface of the fiber saddle is plated with solder. A pre-formed solder structure is bridged over the optical fiber after it is positioned on the fixation surface. The pre-formed structure is melted and then allowed to solidify whereby the optical fiber is affixed to the fiber saddle to prevent dislocation of the fiber. The optically operative device is kept free of contamination by flux during soldering of the optical fiber.
