ABSTRACT:
A laser array submount structure for assembly into a two-dimensional stacked array with precise separation between laser diodes of adjacent submounts. The submount includes a deformable metal layer, such as a soft solder, on one major surface of a laser array support plate. A spacer element having spaced apart ridges is disposed on the opposite major surface. A laser diode array is mounted on a front edge of the support plate. In a cold bonding step, submounts are pressed together causing ridges to penetrate the deformable metal layer to a specified depth. The displaced metal spreads into channels between the ridges, allowing pressing of multiple laser array submounts into stackes of precise total tolerance.
