Abstract
Communication systems and methods are disclosed that route, detect, and decode encoded optical signals at network nodes based on channel codes assigned to the network nodes. In an example communication system, a network hub includes a channel selector that encodes an optical signal with a channel code assigned to one or more network nodes. The channel selector is configured to encode based on a channel selection signal provided to the channel selector and can include one or more fiber Bragg coders. Code-switched communication systems can include one or more nodes configured in ring, tree, or bus architectures.
