Patent ID: 7065113

Claim:
A method for producing a laser-based device, the method comprising: providing a thermally-insulative substrate, the thermally-insulative substrate comprising: a first side having at least one first electrical conductor associated therewith; a second side having at least one second electrical conductor associated therewith, each of said first electrical conductor and said second electrical conductor including a respective electrically-conductive trace; and at least one electrically-conductive via passing between the first side and the second side, the electrically-conductive via electrically coupling the first electrical conductor with the second electrical conductor; electrically coupling an integrated circuit to the at least one first electrical conductor; electrically coupling at least one laser to the at least one second electrical conductor; arranging the integrated circuit and the at least one laser directly opposite one another relative to the thermally-insulative substrate; providing a respective under-fill layer between said thermally-insulative substrate and said integrated circuit and said thermally-insulative substrate and said at least one laser; and electrically coupling the integrated circuit and the laser to the respective electrically-conductive trace through the respective under-fill layer.
