Design of 1D composite photonic crystals with an extended photonic band gap

Abstract

A technique for photonic band gap PBG extension based on mixing photonic crystals with different lattice constants or filling factors is suggested. For the design of photonic crystals with maximal PBG extension the gap map imposition method is utilized. Gap maps for composite photonic crystals based on Si-air structures are calculated and used to predict optimal structures for fabrication.
