Patent ID: 7254301

Claim:
An optical module comprising: a sub-mount, having an optical semiconductor element, which is disposed on a predetermined first surface, and a first alignment portion, which is formed on the first surface; a fiber fixing member, having a fixing groove, which is formed on a predetermined second surface and is for aligning and fixing an optical fiber, a concave mirror, which is disposed with respect to the fixing groove and guides light emitted from one of either the optical fiber that is fixed to the fixing groove and the corresponding optical semiconductor element to the other, and a second alignment portion, which is formed on the second surface; and the optical fiber, fixed to the fixing groove; and wherein of the first alignment portion and the second alignment portion, one of either comprises a guide rail and the other comprises a guide groove that fit with the guide rail, and the sub-mount and the fiber fixing member are aligned and fixed by fitting together of the first alignment portion and second alignment portion, wherein the optical semiconductor element is prepared from the same material and by the same semiconductor process as the sub-mount and thereby formed to be monolithic with the first alignment portion.
