If the periodic structures are fabricated with materials of different dielectric-constants, the photonic band and photonic bandgap may be formed because of the Brag dispersion of the periodic structures to the light wave.
1. The dispersion relations of two dimensional triangular pattern PCs have been studied through plane wave expansion method. The photon energy band structure and photonic band gap mapping of PCs consisting of InP, InGaAsP materials have been calculated.
Using optical transfer matrix method, we numerically investigate the photonic crystals with (AB)~mB~n(BA)~m structure and photonic bandgap, where A and B stand for different dielectric materials, and m and n are the repeating numbers of the units.

Transmission measurements on the cladding of nanostructured fibers having a form of a two-dimensional periodic structure with a pitch less than 500 nm have revealed the existence of a photonic band gap tunable within the range from 930 to 1030 nm.
The positions and amplitudes of third-harmonic resonances at the edges of a photonic band gap strongly depend on the value and sign of the dispersion of refractive indexes of the layers that constitute the photonic crystal.
