Fragility of photonic band gaps in inverse-opal photonic crystals
Inverse-opal techniques provide a promising routine of fabricating photonic crystals with a full band gap in the visible and infrared regimes. Numerical simulations of band structures of such systems by means of a supercell technique demonstrate that this band gap is extremely fragile to the nonuniformity in crystals. In the presence of disorder such as variations in the radii of air spheres an...
متن کاملTwo-dimensional photonic crystals with large complete photonic band gaps in both TE and TM polarizations.
Photonic crystals exhibiting a photonic band gap in both TE and TM polarizations are particularly interesting for a better control of light confinement. The simultaneous achievement of large band gaps in both polarizations requires to reduce the symmetry properties of the photonic crystal lattice. In this letter, we propose two different designs of two-dimensional photonic crystals patterned in...
متن کاملBand Gaps of Diamond Structured Photonic Crystals
In a three dimensional photonic crystal, an artificially formed dielectric structure, periodic along three different axes, when electromagnetic waves interact they periodically modulate the dielectric constant. A photonic band gap may form in these directions prohibiting the propagation of photons for energies that lie within the gap. Under certain conditions, there will be regions of forbidden...
