    摘要: A single-mode optical waveguide with a core, surrounded by a cladding consisting of an inner soft layer and an outer harder layer is described. The outer layer has a grating structure on its inner surface, whose spatial frequency is the same as that of the guided mode. The thickness of the inner cladding is sufficient to keep the grating outside the mode field in undeformed regions of the waveguide, so that normally no out-coupling of the light results. Connections are made by crossing two such waveguides at an angle and pressing them together. This results in deformation of the two waveguides such that the gratings are brought into proximity with the cores. Light is coupled out of one waveguide and into the other in the deformed region, resulting in a self-aligning optical connection. The out-coupled light propagates normal to the waveguide axis, so errors in the crossing angle cause little change in efficiency. Because the cladding system is sufficiently resilient to recover after deformation, the connection is remakeable.

    摘要: A system and method for optical switching of networks in a multi-node computing system with programmable magneto-optical switches that enable optical signal routing on optical pathways. The system includes a network of optical links interconnecting nodes with switching elements that are controlled by electrical control signals. Data transmission is along the optical links and an optical pathway is determined by the electrical control signals which are launched ahead of optical signal. If links are available, an optical pathway is reserved, and the electrical signal sets the necessary optical switches for the particular optical pathway. There is thereby eliminated the need for optical-electrical-optical conversion at each node in order to route data packets through the network. If a link or optical pathway is not available the system tries to find an alternative path. If no alternative path is available, the system reserves buffering. After transmission, all reservations are released.
