Abstract: An apparatus for dissipating heat from a photonic transceiver module. The apparatus includes a top-plate member disposed in a length direction of a package for the photonic transceiver module. The apparatus further includes multiple fins formed on the top-plate member along the length direction from a backend position to a frontend position except at least one fin with a shorter length, forming an elongated void from the backend position to one backend of the at least one fin. Additionally, the apparatus includes a cover member disposed over the multiple fins with a horizontal sheet, two vertical side sheets, and a flange bent vertically from a middle portion of backend of the horizontal sheet. Furthermore, the apparatus includes a spring loaded in the elongated void between the flange and the one backend of the at least one fin to minimize an air gap at the backend of the horizontal sheet.

Abstract: Techniques for coupling light from a waveguide array to a single mode fiber array are described. In an embodiment, lateral misalignment of an array of focusing lenses and an array of optical fiber ferrules held into alignment by a lens holder sub-assembly is compensated by tilting the lens holder sub-assembly with respect to the propagation axis of the light being coupled by the lens holder-subassembly. Since the amount of tilt can be adjusted according to the degree of lateral misalignment, lens holder sub-assemblies manufactured with varying degrees of misalignment may be utilized to couple light into single mode fiber-optic cable. In addition, the same technique can also be used to compensate for other defects as well, such as angular errors in manufacturing or placement of a turning mirror or prism used to direct light into the lens holder sub-assembly.
