Abstract
An array of optical semiconductor devices, an array of lenses and an array of optical fibers are serially arranged in light propagation direction to provide a light axis alignment. At light input ends of the optical fibers, a light shielding plate is positioned. The light shielding plate is provided with light apertures corresponding to light input facets of the optical fibers to decrease leakage light interference between adjacent optical fibers.
