Photonic crystals are periodic dielectric (and/or metallic) structures, with periodicity comparable to a wavelength λ of interest, forming a designable optical medium where light propagation can exhibit unusual properties (Joannopoulos et al.,...

Photonic crystals are periodic optical (nano)structures that are designed to affect the motion of photons in a similar way that periodicity of a semiconductor crystal affects the motion of electrons. Photonic crystals occur in nature and in various...
