Abstract
To provide an optical transceiver module comprising an optical prism for optical communications which has mounting portions, a light emitting portion, light receiving portions, a substrate and a sub-mount that are used as the basis of the optical transceiver module, whose configuration is compact with reduced components which are accurately mounted. A sub-mount is provided on the substrate. The composite optical prism is formed with an optical lens provided with mounting supports and a wavelength division film in an integrated fashion. By using marks on the sub-mount for alignment, the composite optical prism can be mounted accurately on the sub-mount. In addition, the light receiving portions and the light emitting portion can be mounted accurately by using marks for alignment provided on the substrate and the sub-mount.
