Abstract:
1. A laser apparatus, comprising: an array of surface-emitting semiconductor laser diodes formed on a common die and electrically connected in series via series connections; at least one p-n junction in said die disposed under said array, said at least one p-n junction configured to electrically isolate each of said surface-emitting semiconductor laser diodes from parasitic conduction in said die during operation of said array; each said surface-emitting semiconductor laser diode comprises a mesa having a top contact layer and a bottom contact layer formed on a substrate layer, said bottom contact layer having a doping polarity opposite that of said substrate layer to form said at least one p-n junction; and trenches formed in said bottom contact layer between said surface-emitting semiconductor laser diodes to provide trench isolation; wherein at least a portion of the series connections between laser diodes is provided by a submount.
