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.
Journal ArticleDOI
Photonic Band Gap Guidance in Optical Fibers
TL;DR: A fundamentally different type of optical waveguide structure is demonstrated, in which light is confined to the vicinity of a low-index region by a two-dimensional photonic band gap crystal.

Photonic crystals in the optical regime — past, present and future
TL;DR: The aim of this review is to introduce the reader to the concepts of photonic crystals, describe the state of the art and attempt to answer the question of what uses these peculiar structures may have.
Journal ArticleDOI
Complete photonic bandgaps in 12-fold symmetric quasicrystals
TL;DR: It is shown that complete photonic bandgaps—non-directional and for any polarization—to be realized with small air holes in silicon nitride, glass, and even glass make photonic quasicrystals promising for application in a range of optical devices.

Two-dimensional phononic crystals: Examples and applications
Yan Pennec,Jérôme Olivier Vasseur,Bahram Djafari-Rouhani,Leonard Dobrzynski,Pierre A. Deymier +4 more
TL;DR: In this article, the authors present some examples of two-dimensional bulk phononic crystals (i.e., arrays of inclusions assumed of infinite extent along the three spatial directions) and show that the bandwidth of the forbidden band depends strongly on the nature of the constituent materials (solid or fluid), as well as the contrast between the physical characteristics (density and elastic moduli) of the inclusions and of the matrix, the geometry of the array of inclusion, the inclusion shape and the filling factor.
