1. An optical switch, comprising:

  • a unit optical switch inputting n optical signals and outputting n optical signals;

    an optical splitter inputting a single optical signal, splitting the single optical signal into k optical signals, and outputting the k optical signals; and

    an optical selector inputting m optical signals and outputting a single optical signal,wherein the optical splitter comprises m×

    n pieces,the unit optical switch comprises m×

    k pieces,the optical selector comprises n×

    k pieces,(k×

    (m×

    n)) outputs of the optical splitter correspond to (n×

    (m×

    k)) inputs of the unit optical switch,(n×

    (m×

    k)) outputs of the unit optical switch correspond to (m×

    (n×

    k)) inputs of the optical selector, and(n×

    m) optical signals inputted into the optical splitter are output through the (m×

    k) unit optical switch from the optical selector as (n×

    k) optical signals.
