TLDR
In this paper, the authors describe photonic crystals as the analogy between electron waves in crystals and the light waves in artificial periodic dielectric structures, and the interest in periodic structures has been stimulated by the fast development of semiconductor technology that now allows the fabrication of artificial structures, whose period is comparable with the wavelength of light in the visible and infrared ranges.Abstract:
The term photonic crystals appears because of the analogy between electron waves in crystals and the light waves in artificial periodic dielectric structures. During the recent years the investigation of one-, two-and three-dimensional periodic structures has attracted a widespread attention of the world optics community because of great potentiality of such structures in advanced applied optical fields. The interest in periodic structures has been stimulated by the fast development of semiconductor technology that now allows the fabrication of artificial structures, whose period is comparable with the wavelength of light in the visible and infrared ranges.read more

The mathematics of photonic crystals
TL;DR: A photonic crystal, or photonic band gap (PBG) optical material, is an artificially created periodic low-loss dielectric medium in which electromagnetic waves of certain frequencies cannot propagate The range of the prohibited frequencies is called the complete band gap as mentioned in this paper.

Bound states in photonic crystal waveguides and waveguide bends
TL;DR: In this paper, the appearance of bound states in two-dimensional photonic crystal waveguides was investigated and it was shown that their appearance strongly depends on the lattice geometry and cannot be described in a one-dimensional framework.

Fabrication of three-dimensional polymer photonic crystal structures using single diffraction element interference lithography
TL;DR: In this article, the authors describe an approach for recording 3D periodic structures in a photosensitive polymer using a single diffraction element mask with a central opening surrounded by three diffraction gratings oriented 120° relative to one another such that the three first order diffracted beams and the non-differentiated laser beam give a 3D spatial light intensity pattern.

Room temperature photonic crystal defect lasers at near-infrared wavelengths in InGaAsP
TL;DR: In this paper, the authors demonstrated room temperature lasing from optically pumped single defects in a two-dimensional (2D) photonic bandgap (PBG) crystal is demonstrated, where high-Q optical microcavities are formed by etching a triangular array of air holes into a half-wavelength multiquantum-well waveguide.

TL;DR: In this article, a class of π;-conjugated compounds that exhibit large δ (as high as 1, 250 × 10−50 cm4 s per photon) and enhanced two-photon sensitivity relative to ultraviolet initiators were developed and used to demonstrate a scheme for three-dimensional data storage which permits fluorescent and refractive read-out, and the fabrication of 3D micro-optical and micromechanical structures, including photonic-bandgap-type structures.
