Abstract
A reconfigurable laser header assembly, wherein either an n-doped laser substrate structure or a p-doped laser substrate structure can be properly biased, includes a header coupled to a modulated electric (AC) current source, a DC positive bias electric current source, and a DC negative electric current source. A laser is mounted relative to the header, the laser includes a base electric contact and a laser electric contact. An electrical conductor on the header includes first and second metalized regions in electrical connection with the base electric contact, wherein different ones of the modulated electric current source, the bias electric current source, and the DC negative electric current source can be electrically connected to the first metalized region, the second metalized region, and the laser electric contact to properly bias the laser regardless of whether the laser is an n-doped laser substrate structure or a p-doped laser substrate structure.
