High-frequency optoelectronic module

A method for assembling an optical interconnect apparatus is provided. The optical interconnect comprises an integrated circuit chip, and at least one optoelectronic chip positioned on the integrated circuit chip, each of the at least one optoelectronic chip including a 2-dimensional optoelectronic array. The optical interconnect further comprises a first and a second microlens array, a bundle of optical fibers coupled to each second microlens array and supported by a bundle housing, and a block structure supporting the bundle housing to a printed circuit board (PCB).

Parallel optical interconnect

An optical interconnect uses large 2-dimensional matrices of optoelectronic chips. The optoelectronic chips are placed directly above the analog circuitry required to drive them and with the microlens array placed on top of the optoelectronic chip. A single microlens array is assembled directly on top of the 2-dimensional optoelectronic chip. The optoelectronic chips may include vertical cavity surface emitting lasers (VCSEL) for signal generation and p-i-n photodiodes for signal detection. A bundle of optical fibers or waveguides with a layout identical to the optoelectronic chips is used for optical data transfer between constituents of the optical communication system.

Fiber coupling using collimated beams

An interconnect system for coupling light from a laser light source to an optical fiber having a fiber aperture, the interconnect system including a 2-dimensional array of laser light sources, a 2-dimensional array of micro lenses disposed between 10-200 &#x3bc;m distance from the laser light source, between the laser light source and the optical fiber and in registration therewith, each micro lens comprising a micro lens back surface, a micro lens body, a micro lens front surface, and a clear aperture, the micro lens front surface and back surface being shaped to provide a laser beam in the micro lens body of smaller diameter than the clear aperture for focusing the beam onto the fiber aperture.

Method and device for light coupling

An optoelectronic chip assembly including a printed circuit board (PCB) coupled to a substrate, an aperture formed through the printed circuit board and through the substrate, a heat sink, an array of active electro-optical elements mounted in the aperture and connected to a driving chip controlled by the PCB, wherein the driving chip is coupled to the heat sink. Preferably, the assembly further includes a plurality of passive optical elements disposed for optical communication and data transfer with said active electro-optical elements, but thermally isolated therefrom.
