Assignee:
JDS Uniphase Corporation - Milpitas CA
International Classification:
G02B 6/36 H05K 1/14 H05K 5/00
US Classification:
385 93, 385 88, 385 92, 361736, 361752, 361756
Abstract:
The invention relates to an optical sub-assembly package for use in receiver optical sub-assemblies or transmitter optical sub-assemblies in which the electrical connections between the transducer chip, e. g. photo-detector or light source, and the device printed circuit board is made by a single flexible circuit conductor extending through the wall of the package. The package is comprised of a housing and a stiffening plate, which encloses and end of the housing and forms a mechanical support for an end of the flexible circuit conductor.

Abstract:
The present invention relates to a heat sinking tab for dissipating heat directly from an optical sub-assembly (OSA) to a transceiver housing, within which the optical sub-assembly is located. The heat sinking tab includes a mounting plate for mounting on the rear end of a transistor outline (TO) can, and a finger for extending into contact or close proximity to the transceiver housing. The mounting plate also provides a stiffening plate for flexible conductors used to connect the OSA leads to a transceiver printed circuit board (PCB).

International Classification:
G02B006/42
US Classification:
385/088000
Abstract:
The invention relates to a receiver optical sub-assembly (ROSA) for use in a high-speed small-form factor transceiver. The ROSA, according to the present invention, includes a stacked chip design in which a semiconductor micro-bench, upon which the photodiode and trans-impedance amplifier are mounted, is disposed perpendicular to the direction that the light travels. A flexible electrical connector is attached to the semiconductor micro-bench for electrically connecting the ROSA to a host transceiver device. The flexible electrical connector is fixed to the surface of the semiconductor micro-bench with portions cut-out to receive the amplifier and other electrical components extending therefrom. To facilitate assembly, wells are etched from the semiconductor micro-bench corresponding to bumps extending from a mounting flange for the optical coupler.
