摘要： Optical transmission apparatus 100 is provided with laser element 101 and optical fiber 102 and has an optimum position where the efficiency of optical coupling between laser element 101 and optical fiber 102 becomes a maximum. Laser element 101 and optical fiber 102 are fixed at positions shifted from the optimum position in the direction of the optical axis by a value within a range from 10 μm to 150 μm. It is possible to construct the apparatus such that outgoing light of laser element 101 is not parallel to the optical axis of outgoing light from an end face of optical fiber 102 and the outgoing light of laser element 101 is not parallel to the optical axis of light reflected on the end face of optical fiber 102.
