Abstract
Modified laser submounts are positioned in grooves in the surface of a monolithic substrate permitting not only relatively high packing diversities, but also pretesting and easy replacement of any submounts which may later become defective in the field. The assembly may be connected directly to a heat sink or may include an integral microchannel cooler.
Claims6
A laser array assembly comprising a structurally stable substrate having first and second major surfaces, said substrate including a plurality of grooves in said first major surface, each of said grooves having side walls and a bottom portion, each of said side walls including a layer of electrically conducting material, said bottom portion being free of electrically conducting material, said grooves including at least one laser submount, each of said submounts comprising a substrate with a mesa positioned thereon to define a rear extending pedestal and a forward extending portion, said submount including a laser attached to said forward extending portion and being electrically connected to said mesa, said rear extending pedestal being positioned in one of said grooves and electrically and thermally connected to said layers on said side walls.
