ABSTRACT:
An optical package includes a housing composed of two sections, a first section and a second section connectable to the first section. A laser holder is connected to the first section of the housing and adapted to hold a laser assembly. A fiber holder is connected to the second section of the housing and includes a ferrule by which an optical fiber is held. A rod lens is mounted within the housing to focus optical emission from the laser assembly on the optical fiber. The laser assembly includes a semiconductor element. Radial alignment of the semiconductor element and the laser holder is performed before the laser holder is secured to the first section of the housing. Axial alignment of the rod lens and the semiconductor element takes place while the laser holder is being fit in the first section of the housing. The second section of the housing is then moved in a radial direction relative to the optical axis of the semiconductor element and is, then, laser welded to the first section of the housing.
