Lasing action due to the two-dimensional quasiperiodicity of photonic quasicrystals with a Penrose lattice
TLDR
Photonic quasicrystal lasers with a Penrose lattice that does not possess translational symmetry but has long-range order are fabricated, and coherent lasing action is observed due to the optical feedback from quasiperiodicity.Abstract:
We have fabricated photonic quasicrystal lasers with a Penrose lattice that does not possess translational symmetry but has long-range order, and observed coherent lasing action due to the optical feedback from quasiperiodicity, exhibiting a variety of 10-fold-symmetric lasing spot patterns. The lattice constant dependence of lasing frequencies and spot patterns show complicated features very different from photonic crystal/random lasers, and we have quantitatively explained them by considering their reciprocal lattice. Unique diversity of their reciprocal lattice opens up new possibilities for the form of lasers.read more

Metallic Phase with Long-Range Orientational Order and No Translational Symmetry
TL;DR: In this article, a metallic solid with long-range orientational order, but with icosahedral point group symmetry, which is inconsistent with lattice translations, was observed and its diffraction spots are as sharp as those of crystals but cannot be indexed to any Bravais lattice.

Photonic crystals: putting a new twist on light
TL;DR: In this article, the authors describe the photonic bandgap as a periodicity in dielectric constant, which can create a range of 'forbidden' frequencies called a photonic Bandgap.

Localization of light in a disordered medium
TL;DR: In this paper, the authors proposed a disorder-induced phase transition in the electron-transport behavior from the classical diffusion regime, in which the well-known Ohm’s law holds, to a localized state where the material behaves as an insulator.
