| Abstract: | Theoretical study of the optical properties of one dimensional three component photonic band gap structure, which is composed of three alternating dielectric layers of different refractive indices and thickness in a unit cell, is performed. This one dimensional photonic band gap structure exhibits the transparency band and forbidden band. We find that there are several mini bands of the allowed transmission to be created within the photonic band gap region of the structure if a defect designed specially is introduced inside the structure. This characteristic is very important for some practical applications. |
