Abstract: An optical network system, including multiple nodes, an optical switch, and a switch controller, is configured to achieve communication in the optical domain. Each node is configured to receive both high frequency and low frequency inputs, generally utilized for handling data and addressing information, respectively. The two types of information are combined to create an amplitude modulated optical signal. Subsequently, the two types of information are separated by examining the optical power average of the signal being transmitted. Using one portion of the signal for addressing information, the switch controller can perform necessary routing and arbitration functions. Appropriate communications can then be sent back to the nodes and the optical switch to achieve the necessary configuration. The protocol utilized allows for subsequent arbitration and data transmission cycles, allowing the system and switch controller to configure transmission paths and arbitrate any communication issues.

Abstract: An optical lens structure includes a substantially transparent substrate a lens array attached to the substrate with lenses of the lens array situated opposite the substrate and packaging material surrounding at least the periphery of the lens array, the packaging material including at least two alignment holes which are aligned with respect to positions of the lenses. In one example, the structure is fabricated by attaching a lens array to a substrate with lenses of the lens array situated opposite the substrate, surrounding a periphery of the lens array with a packaging material, the packaging material being attached to the substrate, planarizing the packaging material, and providing alignment holes through the packaging material.

Abstract: A method of positioning an optoelectronic device, for example a vertical cavity surface emitting laser, onto an optical fiber connector and maintaining that exact alignment while testing the quality of the optical output prior to applying an adhesive to make the interface permanent. The method includes the utilization of a multi-piece fixture which clamps the elements into position, allows for testing, and provides a fixture to maintain position throughout the curing process.
