Abstract:
1. An integrated semiconductor laser diode module comprising: a first wafer including a first substrate and at least one first laser diode on a first surface of the first substrate, the at least one first laser diode being made of a nitride semiconductor; a second wafer including a second substrate and at least one second laser diode on a second surface of the second substrate, the at least one second laser diode being made of one of (a) a gallium arsenide semiconductor, (b) an aluminum gallium indium phosphide semiconductor, and (c) an indium phosphide semiconductor; and a joining member for joining the first wafer to the second wafer so that said first surface overlaps said second surface, wherein the at least one first laser diode has a first resonator, the at least one second laser diode has a second resonator whose length is greater than a length of the first resonator, and the at least one first laser diode is joined to the at least one second laser diode in a manner that the first resonator and second resonator are substantially parallel in a lengthwise direction thereof, and at least one of (a) emitting facets of the first resonator and second resonator, and (b) reflecting facets of the first resonator and second resonator are not on the same plane.
