Reconfigurable laser header

A reconfigurable laser header assembly, wherein either an n-doped laser substrate or a p-doped laser substrate can be properly biased, the reconfigurable laser header assembly comprising:

• a header coupled to a modulated AC electric current source, a DC positive bias electric current source, and a DC negative electric current source;
• an electrical conductor on the header including first and second metalized regions;
• and
• a laser of the type selected from the group consisting of an n-doped laser substrate, and a p-doped laser substrate;
• wherein the n-doped laser substrate includes:
• an n-substrate with a base anode contact, and a p-semiconductor layer with a laser cathode contact;
• wherein the p-doped laser substrate includes a p-substrate with a base cathode contact, and an n-semiconductor layer with a laser anode contact;
• wherein the electrical conductor is electrically connected to the base anode contact of the n-doped laser substrate or to the base cathode contact of the p-doped laser substrate,
• wherein the modulated AC electric current source and the DC positive bias electric current source are electrically connected to the laser anode contact with first relocatable conductors or to the base anode contact via the first relocatable conductors electrically connected to the first and/or second metalized regions;
• and
• wherein the DC negative electric current source is electrically connected to the laser cathode contact with a second relocatable conductor or to the base cathode contact via the second relocatable conductor electrically connected to the first and/or the second metalized regions;
• whereby the laser is properly biased regardless of whether the laser is an n-doped laser substrate structure or a p-doped laser substrate structure.
