The present invention provides a free space optical switching and routing system utilizing a switchable grating based approach together with novel noise suppression techniques. This family of devices provides for an optical switching and routing system that is useful for interconnecting any of an input array's optical channels to any of an output array's optical channels. The incorporation of free space switched grating based routing in the present invention has several distinct advantages including compactness, a reduction in insertion loss and the number of required switching devices and control signals, and improvements in switch isolation, noise and crosstalk suppression, spurious reflections, data skew, and compactness.
