摘要:
A wafer scale implementation of an opto-electronic transceiver assembly process utilizes a silicon wafer as an optical reference plane and platform upon which all necessary optical and electronic components are simultaneously assembled for a plurality of separate transceiver modules. In particular, a silicon wafer is utilized as a "platform" (interposer) upon which all of the components for a multiple number of transceiver modules are mounted or integrated, with the top surface of the silicon interposer used as a reference plane for defining the optical signal path between separate optical components. Indeed, by using a single silicon wafer as the platform for a large number of separate transceiver modules, one is able to use a wafer scale assembly process, as well as optical alignment and testing of these modules.

The invention relates to a coupling location (11) which can for example be used to couple light (31) emitted by a diode (21) into an optical waveguide (15). According to the invention, the light-emitting diode (21) is aligned at stop surfaces (22) in such a manner that the coupling of light is facilitated with high precision along an axis of transmission (30). The optical fibers (33) in the optical waveguide (15) are advantageously coaxially disposed around a core (34) that is impervious to light so that said core is illuminated with comparable light intensity taking into consideration the light intensity distribution (31) of the light-emitting diode (21) which is configured as a Gaussian emitter.

This invention relates to an optical transmitter, receiver or transceiver module, and more particularly, to an optoelectronic connector. The optoelectronic connector comprises: (1) a mounting structure; (2) an array of optoelectronic devices adapted to the mounting structure, the optoelectronic devices having at least a first end; (3) an array of optical elements, the array of optical elements having at least a first end; (4) the first end of the array of optical elements proximate to the first end of the array of optoelectronic devices in such a manner that one or more optical elements is positioned relative to one or more optoelectronic devices; and (5) a heat spreader passing along a surface of a head region of the mounting structure. The mounting structure may be a flexible printed circuit board. Thermal vias or heat pipes in the head region may transmit heat from the mounting structure to the heat spreader. The heat spreader may provide mechanical rigidity or stiffness to the heat region. In another embodiment, an electrical contact and ground plane may pass along a surface of the head region so as to provide an electrical contact path to the optoelectronic devices and limit electromagnetic interference. In yet another embodiment, a window may be formed in the head region of the mounting structure so as to provide access to the head spreader. Optoelectronic devices may be adapted to the head spreader in such a manner that the devices are accessible through the window in the mounting structure.

A device or array of arrayed optical subassemblies includes modular units (70, 80) called one channel sub-assemblies. Each of the one channel sub-assemblies includes a small format optical subassembly attached to a substrate (40) and an optical coupling element all of which is connected to a base (50). The optical coupling element includes a focusing element (20) and a ferrule receiving bore (32). The arrayed device makes it possible to remove and replace one of the one channel sub-assemblies with another one channel sub-assembly. The small format optical subassembly of the one channel sub-assembly may be a transmitter to a receiver. Thus, the device is a modular, high-density, multiple optical transmitter/receiver array.
