Complete photonic bandgaps in 12-fold symmetric quasicrystals
Article Abstract:
It was demonstrated that quasicrystalline lattices can also possess photonic bandgaps. This enables complete photonic bandgaps to be realized with small air holes in silicon nitride and in glass.

Experimental measurement of the photonic properties of icosahedral quasicrystals
Article Abstract:
Quasicrystalline structures have frequency ranges in which the propagation of light is forbidden to make them suitable for scientific and technological applications for which photonic crystals are used. These three dimensional icosahedral quasicrystals yield uncomplicated spectra that allows experimentation.

Wave and defect dynamics in nonlinear photonic quasicrystals
Article Abstract:
The light launched at different quasicrystal sites travels through the lattice in a way equivalent to quantum tunneling of electrons in a quasiperiodic potential. Dislocation dynamics is observed when crystal sites are allowed to interact with each other and the experimental results apply to photonics and other quasiperiodic systems such as matter waves in quasiperiodic traps, generic pattern-forming systems as in parametrically excited surface waves, liquid quasicrystals, and the atomic quasicrystals.
