Light source device for an optical head apparatus and method relating thereto |
摘要 |
A light source device for an optical head apparatus comprises at least one laser diode chip and a semiconductor substrate integral with the laser chip. The light source device is formed in a recess of the semiconductor substrate for aligning the laser diode chip on a surface of the semiconductor substrate by a semiconductor processing technique. The recess comprises a first side surface for defining a laser beam emitted from the laser diode chip in an optical axial direction and a second side surface for defining a direction perpendicular to the optical axial direction.
