Opto-electronic component support esp. for laser diode circuit - has low thermal conductivity metal insert, with component mounted on good thermal conductor

摘要

The laser support includes a relatively poor thermal conductor material (5), in which there is a good thermal conductor material insert (50). Both pieces of the support are metal. The poor thermal conductor material is pref. a Fe-Ni-Co alloy, and the insert may be Cu or W. A ceramic substrate mounting is used for the optoelectronic circuit, which is coupled to an optical fibre. ADVANTAGE - Prevents soldering heat damaging optoelectronic components, when attaching optical fibre.
