Abstract: The optical integrated circuit includes a substrate; and, a plurality of optical elements supported by the substrate being optically coupled with each other, each optical element comprising silicon nanoclusters and having a desired opto-physical interaction with light impinging thereon. These optical elements may be, for example, optical sources, optical waveguides, optical switches and optical detectors.

Abstract: An integrated circuit having circuit structures, including at least one of logic elements and memory elements. A core is disposed at an interior portion of the integrated circuit. The core contains core power contacts and core ground contacts for providing electrical power to the circuit structures during functional operation of the integrated circuit. A peripheral is disposed at an edge portion of the integrated circuit. The peripheral contains signal contacts for sending and receiving electrical signals between the circuit structures and external circuitry. The peripheral also has peripheral power contacts and peripheral ground contacts for providing electrical power to the circuit structures during testing of the integrated circuit. The peripheral power contacts are redundant to at least some of the core power contacts, and the peripheral ground contacts are redundant to at least some of the core power contacts.
