Abstract:
1. An optical device, comprising: a substrate interface board; a heat sink carrier having guide pins thereon, the guide pins being integral to the heat sink carrier; an optical sub-assembly passively aligned to the heat sink carrier via the guide pins; an electrical connector mounted to the substrate interface board, the electrical connector adapted to mate with a corresponding connector on a host board to provide a connection with the host board; an external carrier in which the substrate interface board, heat sink carrier and optical sub-assembly are mounted, wherein the guide pins also permit passive alignment between the heat sink carrier with optical sub-assembly to the substrate interface board; and a flexible joint between the heat sink carrier and the external carrier to alleviate mechanical stress on the optical device when the electrical connector mates with the connector on the host board, the size of the flexible joint being dependent on thermal conductivity of the flexible joint.
