发明名称 Optical pickup projecting two laser beams from apparently approximated light-emitting points
摘要 An integrated type optical pickup module apparently approximates a plurality of light-emitting points of semiconductor lasers. An optical element is interposed between first and second semiconductor lasers. The optical element has first and second reflecting surfaces perpendicular to each other. The first and second reflecting surfaces reflect laser beams projected from the first and second semiconductor lasers, respectively. The optical element further has a mounting surface perpendicular to both the first and second reflecting surfaces. The optical element is mounted, via the mounting surface of the optical element, to a submount having a top surface on which the first and second semiconductor lasers are mounted. Heterojunction surfaces of the first and second semiconductor lasers may be substantially perpendicular to the first and second reflecting surfaces, respectively.
