Abstract:
The method of fabricating an integral stack of laser diodes, said method comprising the steps of assembling a plurality of electrically conducting submounts in a bonding jig with a laser diode sandwiched between each pair of adjacent submounts where each submount has a relatively narrow ridge portion extending therefrom, placing solder preform between each submount and an adjacent laser diode, heating the stack under pressure at a temperature for a time to form an integral stack with said ridges extending in a like direction and forming a plurality of parallel and spaced apart ridges, metallizing each of a plurality of grooves in an electrically insulating carrier having a plurality of grooves to correspond to said ridges, placing solder in each of said grooves, mating the stack with said carrier, and heating the assemblage for a time under pressure to bond the stack to the carrier.
