Problems solved by technology

But the problem is that due to the high high frequency induction heating, the local temperature rises
There is a risk that uncured adhesive may flow or drift, contaminating the lens or the front surface of the optical semiconductor device
Therefore, it is difficult to adopt this method

Abstract

A method of producing an optical module in which with respect to a housing having an optical part received therein, an optical semiconductor device of a package structure is center-aligned to be positioned on an optical axis of the optical part and is attached to the housing. The method comprises the steps of: applying an ultraviolet-or-heat-curable resin onto a joint surface between the housing and the optical semiconductor device and curing the ultraviolet-or-heat-curable resin 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 is applied onto the outer side of the ultraviolet-or-heat-curable resin to reinforce adhesion between the optical semiconductor device and the housing.

Description

technical field [0001] The present invention relates to a method of manufacturing an optical module in which compact optical semiconductor devices and optical components such as lenses are aligned with each other and fixed in a housing. Specifically, the present invention relates to a method of manufacturing an optical assembly, the method comprising the steps of: applying an ultraviolet or heat curable resin to a joint portion between an optical semiconductor device and a case; irradiating the joint with ultraviolet rays The resin at the part; and the resin at the bonding part is heated to fix the optical semiconductor device to the case. Background technique [0002] An optical component is a device in which an optical semiconductor device (such as a semiconductor light-emitting device such as a laser diode or a semiconductor photodetection device such as a photodiode) and various optical components (such as a lens, an optical fiber ferrule, etc.) are aligned with each oth...
