ABSTRACT:
The present invention encompasses both a method and an apparatus for fabricating a multiple beam semiconductor laser array, wherein the laser includes a plurality of semiconductor laser dies affixed in a linear fashion to a supporting heatsink. Accurate alignment of the lasers and control of interlaser spacing is achieved through the use of alignment structures formed on the mounting surface of the heatsink. Once assembled, the alignment structures remain in an abutting relationship with the ridge waveguides present on each of the semiconductor lasers. The method not only enables the accurate placement of the laser diodes relative to one another so as to reduce interlaser spacing error, but also eliminates the need for multiple-step alignment operations to produce the multiple diode laser array.
