Abstract:
1. An arrangement comprising: a photonic band-gap assembly having a photonic band-gap in first, second, and third directions that are not all coplanar, the photonic band-gap assembly comprising: at least one input wave guide in a first plane, the first plane being defined by the at least one input wave guide and the first and second directions; and at least one output wave guide non-coplanar with the at least one input wave guide, wherein the at least one output wave guide is in a second plane different from the first plane, the second plane being at least partially defined by the at least one output wave guide and the third direction; and wherein the photonic band-gap assembly includes at least one routing element responsive to signals to selectively route a signal from one or more of the at least one input wave guide to one or more of the at least one output wave guide.
