ABSTRACT:
A laser array for a large number of lasers which are manufactured on a single metal level is taught. Briefly stated the cavity length of the lasers are shortened so as to provide for metal lands or traces to be disposed adjacent to rear facets of the laser for eventual interconnection with pads. The diminution in cavity length does not degrade laser performance or characteristics, while performance and characteristics amongst adjacent lasers is similar.
