Photonic Band Gap

Photonic Band Gap materials, also known as photonic crystals, are materials which have a band gap due to a periodicity in the materials dielectric properties.

The band gap in photonic crystals represents the forbidden energy range where wave behaving photons can not be transmitted through the material. By imitating the periodicity of photonic crystals one can tailor the specific band gap of a structure by defining a pattern with repeating regions, typically holes in a square or hexagonal arrangement, which alternates between materials with high and low dielectric constant.

NILT has long-standing experience in the fabrication of 1D and 2D photonic band gap structures.
