Physics World, 1992 Many major discoveries in physics this century originate from the study of waves in periodic structures. Examples include X-ray and electron diffraction by crystals, electronic band structure and holography. Analogies between disciplines have also led to fruitful new avenues of research.

AIP Advances, 2018 In this study, We theoretically realized the enlargement of the photonic crystal band gap by a photonic heterostructure containing Dirac semimetal layer. At the same time, since the dielectric constant of the Dirac semimetal changes with its Fermi level,

Effects of Random Link Removal on the Photonic Band Gaps of Honeycomb Networks [PDF]
, 2010 We explore the effects of random link removal on the photonic band gaps of honeycomb networks. Missing or incomplete links are expected to be common in practical realizations of this class of connected network structures due to unavoidable flaws in the ...

Larger Two-Dimensional Photonic Band Gaps [PDF]
Physical Review Letters, 1996 Absolute photonic band gaps in two-dimensional square and honeycomb lattices of circular cross-section rods can be increased by reducing the structure symmetry. The addition of a smaller diameter rod into the center of each lattice unit cell lifts band degeneracies to create significantly larger band gaps. Symmetry breaking is most effective at filling

Emergence and control of photonic band structure in stacked OLED microcavities
Nature Communications, 2021 Understanding and manipulating the photonic band structure formed in stacked Fabry-Pérot microcavity organic light-emitting diodes (OLEDs) is key to optimizing their performance. Here, through intelligent device design, the authors tune the photonic band

Photonic Bloch Waves and Photonic Band Gaps [PDF]
, 1995 Photonic band gap materials are dielectrics with a synthetic, three dimensional, multiply periodic microstructure (lattice constant of order the optical wavelength) whose distinguishing feature is a very large modulation depth of refractive index. When appropriately designed, these "photonic crystals" exhibit ranges of optical frequency where light ...

Photonic band-gap structures [PDF]
Journal of the Optical Society of America B, 1993 The analogy between electromagnetic wave propagation in multidimensionally periodic structures and electron-wave propagation in real crystals has proven to be a fruitful one. Initial efforts were motivated by the prospect of a photonic band gap. a frequency band in three-dimensional dielectric structures in which electromagnetic waves are forbidden ...
