Method of producing an optical module

摘要

A method of producing an optical module in which with respect to a housing (12) having an optical part (a lens 10) received therein, an optical semiconductor device (such as a laser diode 14) of a package structure is center-aligned to be positioned on an optical axis of the optical part and is attached to the housing (12). The method comprises the steps of: applying an ultraviolet-or-heat-curable resin (30) onto a joint surface between the housing and the optical semiconductor device and curing the ultraviolet-or-heat-curable resin (30) by external irradiation with ultraviolet rays in the condition that the optical axes of the lens and the laser diode are center-aligned and joined with each other to thereby temporarily fix the optical semiconductor device to the housing; and complementarily curing non-irradiated portions of the ultraviolet-or-heat-curable resin by heating. Preferably, a heat-curable resin (40) is applied onto the outer side of the ultraviolet-or-heat-curable resin to reinforce adhesion between the optical semiconductor device and the housing.
