LASER MODULE FOR AN OPTICAL READING/WRITING HEAD AND METHOD FOR THE PRODUCTION THEREOF

摘要

The invention relates to a laser module for an optical reading/writing head, comprising at least one edge emitting semiconductor laser (10, 11) that is arranged on a carrier (1). The carrier is produced by shaping a copper foil and additionally has a primary carrier surface (2) on which the semiconductor laser (10, 11) is arranged and a reflecting surface (6) that is connected to the primary carrier surface (2) at a predetermined angle, e.g. 45 DEG , said reflecting surface deflecting the light emitted by the semiconductor laser (10, 11) in a predetermined direction. The carrier (1) can also have secondary carrier surfaces (3, 4, 5) on which other optical/electronic components are mounted in such a way that the contact surfaces of possibly all components are located on a plane and can be contacted with the strip conductors of a film printed board in a TAB process. Matrixes produced according to the LIGA method are used to shape the metal foils into a carrier (1). The laser module can be universally used and can be economically produced due to the possibility of applying well-established and highly automated method steps.
