Abstract
[Problems] To accommodate a plurality of optical semiconductor elements in one package with their optical axes aligned highly precisely. [Means for Solving the Problems] An optical transmission module includes an optical transmission unit, a carrier to become a base, a semiconductor optical amplification element mounted on the carrier through a first sub-carrier, first and second lenses fixed on the carrier through first and second lens holders, an element supporting member and an optical isolator fixed on the carrier, a third lens holder supported by the element supporting member, a third lens and a small carrier individually fixed in the third lens holder, and a semiconductor laser element mounted on the small carrier through a second sub-carrier.
