    摘要: An optical switch having switch mirror arrays controlled by scanning beams that reduce the amount of electrical connections required and reduce the complexity for constructing large optical switches. Movement of the switch mirror arrays is controlled by one or more scanning beams. The optical switch includes one or more arrays of optical switch inputs and outputs and one or more arrays of movable mirrors to direct light beams from the optical switch inputs to the optical switch outputs. The optical switch also includes one or more control elements to control the movable mirrors based on scanning beams directed to the one or more control elements.

    摘要: A scalable optical switch that uses substrates to multiplex and demultiplex input and output optical signals for optical networks. The switch includes a plurality of input fibers each configured to carry a plurality of lambda signals, a first stack of substrates, each of the substrates coupled to one of the input fibers and configured to demultiplex the lambda signals received on the input fiber by wavelength respectively, a plurality of output fibers, and a switching matrix configured to switch the demultiplexed lambda signals from the first stack of substrates to the plurality of output fibers. In one embodiment, the switch further includes a second stack of substrates coupled between the switching matrix and the output fibers. Each of the substrates of the second stack is configured to multiplex the switched lambda signals onto one of the output fibers respectively. In an alternative embodiment, the second stack of substrates is replaced with a fixed mirror so that the input fibers can also be used as output fibers. In other embodiments of the invention, alignment plates are used to align the substrates of the first stack and/or the second stack respectively. In yet other embodiments, the optical switch of the present invention is scalable to form a large photonic switching system where individual switches are each used for specific bands or sub-bands of amplification.
