1. A wavelength-tunable grating device comprising:

  • a support frame for supporting a body of material;

    a body of material including an optical grating, the body attached to the support frame on opposite sides of the grating; and

    a movable body for pushing of pulling laterally on the body or material to elastically flex the body and induce a tensile strain therein, thereby altering the resonant resonant wavelength of the grating.
