OPTICAL INTERFACE UNIT
First Claim
1. A method for coupling an optoelectronic device to a conventional latch and for receiving a conventional optic fiber connector, said method comprising:
- providing a fiber stub array and inserting a pair of guide pins therein;
providing a two part VCSEL plate and aligning a VCSEL array and a photodiode to said two part VCSEL plate, wherein at least one of said two part VCSEL plate is made of a weldable material;
inserting and fastening said fiber stub array in a cradle;
coupling and fastening said fiber stub array and cradle combination to a connector latch;
inserting a conventional ferrule to the connector latch;
placing said fiber stub array, cradle, connector latch, and ferrule combination next to said VCSEL plate, VCSEL array, and photodiode combination and adjusting said two combinations while actively aligning said two combinations; and
welding a portion of said two part VCSEL plate to said cradle.

Abstract
In an exemplary embodiment of the present invention, an optical interface unit provides an interface between an optoelectronic device and industry standard MTP/MPO connectors. The optical interface unit axially aligns the core of a fiber with the optoelectronic device and interfaces that fiber to the standardized connector. In addition, the optical interface unit further provides a standardized interface for visible contact connection between the individual fiber stubs and the terminated fibers in the standardized connector. The optical interface unit therefore maximizes coupling from the optoelectronic device with the standardized connector.

6. A method for interfacing an optoelectronic device to an optic fiber connector, said method comprising:
-
aligning a VCSEL array and a monitor diode to a two part VCSEL assembly, said two part VCSEL assembly comprising a ceramic substrate and a weld plate;
press fitting at least one guide pin into a base unit and sliding said passively aligned VCSEL assembly onto the guide pin;
sliding a fiber stub array onto said at least one guide pin until contact is made between the fiber stub array and a portion of the aligned VCSEL assembly;
coupling a connector latch to the base unit by keying the connector latch to the base unit and then fastening the connector latch by at least one of epoxy, detents, and pressure force from a screw;
inserting the optic fiber connector into the connector latch until latching occurs between the connector latch and the optic fiber connector;
rotating the aligned VCSEL array assembly in at least one of x, y, and theta directions with respect to the base unit;
actively aligning the VCSEL array assembly to a plurality of optic fibers by monitoring signals generated by the VCSEL array; and
welding the weld plate to the base unit. - View Dependent Claims (7, 8, 9, 10)
