OPTICAL SWITCHING DEVICE AND SIGNAL SWITCHING SYSTEM

摘要

An optical switching device, comprising an optical switching apparatus, the optical switching apparatus comprises N-number of optical components for combining, the optical component for combining comprising at least k-number of inputs and at least one output; N-number of optical components for splitting, the optical component for splitting comprising at least one input and at least k-number of outputs; N is larger than or equal to 1 and k is larger than 1; a Cyclic AWG supporting at least k-number of cycles, the Cyclic AWG comprising at least N-number of inputs and at least N-number of outputs; the outputs of the N-number of optical components for combining are connected to the N-number of inputs of the Cyclic AWG; the N-number of outputs of the Cyclic AWG are connected to the inputs of the N-number of optical components used for splitting; the optical components for splitting are used to split the optical signals of different cycles outputted by the Cyclic AWG to different outputs of the optical components for splitting to be outputted.
