Photonic Crystals in One, Two and Three … A photonic crystal is an optical nanostructure in which the refractive index changes periodically. This affects the propagation of light in the same way that the structure of natural crystals gives rise to X-ray diffraction and that the atomic lattices (crystal structure) of semiconductors affect their conductivity of … See more Photonic crystals are composed of periodic dielectric, metallo-dielectric—or even superconductor microstructures or nanostructures that affect electromagnetic wave propagation in the same way that the periodic potential See more The fabrication method depends on the number of dimensions that the photonic bandgap must exist in. • Examples … See more The photonic band gap (PBG) is essentially the gap between the air-line and the dielectric-line in the dispersion relation of the PBG system. To design photonic crystal … See more • Animal coloration – General appearance of an animal • Animal reflectors • Colloidal crystal – Ordered array of colloidal particles See more Photonic crystals have been studied in one form or another since 1887, but no one used the term photonic crystal until over 100 years later—after Eli Yablonovitch and Sajeev John published … See more Higher-dimensional photonic crystal fabrication faces two major challenges: • Making them with enough precision to prevent scattering … See more Photonic crystals are attractive optical materials for controlling and manipulating light flow. One dimensional photonic crystals are already in widespread use, in the form of See more
