ABSTRACT:
A diffraction grating can be tuned by varying the spacing of the rows of the diffraction grating. The diffraction grating is comprised of rows of an electrically conductive material disposed on a deformable material. The deformable material is transparent to a light of numerous wavelengths. A means for applying a voltage on the rows of the electrically conductive material is provided to change the spacing of the rows, thus changing which wavelength of light is diffracted.
