Abstract:
1. A sub-mount adapted for AC and DC operation of devices mountable thereon, the sub-mount comprising: a base substrate including a first surface and a second surface, the first surface being different from the second surface; a conductive pattern on the first surface; a first pair of first and second electrodes on the second surface of the base substrate; a second pair of first and second electrodes on the second surface of the base substrate; and a plurality of vias extending through the base substrate between the first surface and the second surface, wherein: the conductive pattern includes a first set of mounting portions and two via portions along a first electrical path between the first pair of first and second electrodes, and a second set of mounting portions and two via portions along a second electrical path between the second pair of first and second electrodes, the first path being independent of the second path, and each of the via portions connecting respective portions of the conductive pattern to a respective one of the electrodes of the first and second pair of first and second electrodes through a respective one of the vias.
