Abstract
Optical networks can comprise a branch structure with the de-multiplexing/multiplexing structure that operates to disperse a plurality of optical bands. Thus, the optical network comprises an optical network connection with a common optical channel, a plurality of de-multiplexed branch optical service connections and the de-multiplexing/multiplexing structure. In some embodiments, one optical band can be used to deliver input from a common channel to the branch node and the other optical band can carry output along the common channel from the branch node. The de-multiplexing/multiplexing element can be an arrayed waveguide grating. The AWG can have desirable architecture to efficiently provide the corresponding functions with respect to the two optical bands. Appropriate photodetectors and light sources can be associated with the AWG.
