Image of FIG. 1.
FIG. 1.

(a) A schematic drawing of multi beam interference by amplitude mask with three little holes. The dark diamond-shaped area is the interference region of these beams. (b) Computer simulated interference intensity distribution for two-dimensional decagonal photonic quasicrystal lattices. (c) The computer simulated inverse Fourier transform of two-dimensional decagonal quasicrystal lattices. (d) and (e) Simulated diagrams of far-field diffraction pattern and Brillouin-zone spectroscopy pattern of decagonal quasicrystal lattices, respectively.

Image of FIG. 2.
FIG. 2.

Schematic representation of the experimental scheme for the generation and analysis of two-dimensional photonic quasicrystal lattices in LiNbO3:Fe crystal. λ/2, half-wave plate; S, shutter; SF, spatial filter; L, converging lens; BS, beam splitter; M, mirror; ID, iris diaphragm; RD, rotating diffuser; LN, LiNbO3:Fe crystal. The amplitude mask with five little holes and the five-beam launching scheme are shown in the inset.

FIG. 3.

The induced two-dimensional photonic quasicrystal lattices in LiNbO3:Fe crystal. (a) The intensity pattern of the quasicrystal lattice wave which is captured at the front surface of the LiNbO3:Fe crystal in the initial time. (b) Image of the induced two-dimensional decagonal photonic quasicrystal lattices in LiNbO3:Fe crystal. (c)-(f) The diffraction light spot patterns of the induced quasicrystal lattices illuminated by each of the beams produced from small holes, separately. (g) Far-field diffraction pattern of the induced quasicrystal lattices is imaged using a CCD. (h) Brillouin-zone spectroscopic image of induced quasicrystal lattice. (i) Image of the induced quasicrystal lattices which are stored in the dark room for 4 weeks.

Image of FIG. 4.
FIG. 4.

Numerical simulation of more higher-order rotational symmetry quasicrystal lattices which are produced by different amplitude masks. (a) and (d) Pictures are the amplitude masks with eight and twelve little holes, respectively. (b) and (e) Simulated interference intensity distribution for two-dimensional octagonal and dodecagonal quasicrystal lattices, respectively. (c) and (f) Simulated diagrams of far-field diffraction patterns of two-dimensional octagonal and dodecagonal quasicrystal lattices, respectively.
