23 . An arrangement comprising:

a photonic band-gap assembly comprising at least one input guide and at least one output guide; the photonic band-gap assembly including at least one routing element responsive to signals to selectively route a signal from the input wave guide to one or more of the output wave guides, wherein the at least one routing element responsive to signals further includes:

a micro-electro-mechanical systems (MEMS) element.

81 . A photonic routing system comprising:

a least one input port and a plurality of output ports

a photonic structure switchable between at least two photonic configurations, a first of the photonic configurations being operative to direct photon signals received at the at least one input port to a first of the output ports and a second of the photonic configurations being operative to direct photon signals received at the at least one input port to a second of the output ports, wherein the photonic structure is responsive to a control signal to selectively switch between the first of the photonic configurations and the second of the photonic configurations; and

a mechanically movable element responsive to the control signal to move from a first state to a second state, wherein the mechanically movable element is a MEMS element.
