Abstract:
An optical module includes an emitter-side mounting substrate, a receiver-side mounting substrate and an external waveguide substrate. The mounting substrate is provided with a waveguide having a core and a pair of fitting recesses. The external waveguide substrate is provided with an external waveguide having a core, a pair of fitting tabs and a lap joint portion. As the fitting tabs are fitted into the respective fitting recesses, the mounting substrate) and the external waveguide substrate are joined together, the two cores are aligned with each other, and the lap joint portion is positioned to overlap the mounting substrate.
