One-dimension (1D) photonic crystals have been widely used in silicon photonics due to its simple structure and multiple working regimes: difraction, Bragg reflection, and sub-wavelength regimes. Due to their periodic modulation of the refractive index they exhibit a band-structure for photons. After summariz-ing the theory of photonic bandgap materials, the preparation and linear optical properties of 1D, 2D, and 3D silicon-based photonic crystals are discussed. The original discovery of Photonic Crystals was reviewed by Yablonovitch in his popular SCIENTIFIC AMERICAN article. This feature results in a spectral region over which no light can propagate within such a material, known as the photonic band gap (PBG).
