Abstract : The present invention relates to an optical beam deflector, beam modulator and beam shaper using a Raman-Nath diffraction methodology generated by a plurality of writing laser beams focused onto a bulk optical material having anisotropic optical characteristics for deflection, modulation, and shaping of a beam of light incident to the diffraction grating. The writing laser beams are split from a tunable laser source and the choice of the desired operational characteristic, i.e. deflector, modulator, and shaper are chosen by selective manipulation of the source beam of and the derived split beams.
