In the optical element fixing method, when optical elementis adhesively fixing memberby using the optical-curing adhesive, the optical-curing adhesive is applied on at least one of the adhesion sections of the optical element and the adhesive section of the fixing member, and the optical-curing adhesive is irradiated with the light from the light source through the loading jig while the load is being applied to the adhesion fixing section through loading jigmade of light-transmissive material.

Method of fixing an optical element and method of manufacturing optical module including the use of a light transmissive loading jig

An optical bidirectional modulehaving therein light emitting elementwhich transmits optical signal to the end facet of the optical fiber, light receiving elementwhich receives optical signal from the end facet of the optical fiber and stair-shaped multi-level grating, wherein the stair-shaped multi-level grating separates the first light path between the end facet of optical fiber and the light emitting element and the second light path between the end facet of optical fiber and the light receiving element by a different wavelength of each optical signal, when the module mixes and separates optical signal with different wavelengths traveling in opposite directions related to the end facet of the optical fiberused for bidirectional optical fiber communication by means of a wavelength multiplex system.
