1. A switchable optical component comprising:

  • an ESBG element;

    first and second electrodes positioned on opposite sides of said element for selectively applying an electric field thereacross;

    at least one optical input path to said element and at least one optical output path from said element, at least one of said input optical paths and said output optical paths being guided wave optical paths;

    the optical effect which the element has on optical signals inputted thereto, and thus any optical signal appearing on said at least one output, varying as a function of the electric field applied across the element.
