ABSTRACT:
A component package for the semiconductor laser and photodiodes of an audio or video disk recording and/or playback system includes a wiring substrate which provides electrical wiring to these components and in addition provides support for the same. The substrate is configured to include independently flexible fingers or the like, with the laser and the photodiodes being supported by different fingers. The substrate is itself supported within a package body which is filled with a protective gas. This arrangement allows the electro-optical elements to be provided in chip form without independent protective cases.
