Patent ID: 7158549

Claim:
An optical subassembly comprising: a substrate with electrically conductive interconnects thereon, the substrate including first and second opposed surfaces and at least a portion of the electrically conductive interconnects being positioned on the first surface; a heat spreader having a surface; a submount including a submount mounting surface and a component mounting surface, one of the submount mounting surface and the component mounting surface including an angle, and the submount positioned on one of the surface of the heat spreader and the first opposed surface of the substrate such that the component mounting surface is positioned at the angle relative to the first opposed surface of the substrate; an optoelectric device with a component interconnect positioned on the component mounting surface and the component interconnect of the optoelectric device coupled to the electrically conductive interconnects of the substrate, the optoelectric device being thermally coupled to the heat spreader through the submount to provide a low thermal resistance between the optoelectric device and the heat spreader; and an encapsulant structure mounted on the first opposed surface of the substrate and hermetically enclosing the optoelectric device.
