Abstract: A structure having first and second electrical conductors disposed on a surface of the structure and a bridging conductor connected between the first electrical conductor and the second electrical conductor with portions disposed over the surface of the structure. The bridging conductor includes a plurality of stacked, multi-metal layers, each one of the multi-metal layers having: an electrically conductive layer; and a pair of barrier metal layers, the electrically conductive layer being disposed between and in direct contact with the pair of barrier metal layers.

Abstract: A system includes a network having multiple network nodes each configured for free-space optical communication. Each network node includes one or more apertures through which optical beams are transmitted and received over optical links. The optical links include (i) a traffic link that transports higher-rate traffic between nodes and (ii) an acquisition/tracking link that transports lower-rate signals used to establish and maintain location knowledge of other nodes. Each network node also includes a network processor configured to determine one or more backup paths through the network. Each network node further includes a beam steering unit configured to redirect an optical beam from the traffic link onto the acquisition/tracking link to create a backup traffic link.
