    Abstract

    We give a theoretical analysis of the photonic band gap in a one-dimensional semiconductor-organic photonic crystal containing a period of AlN/3-octylthiophenes (P3OT) bilayer. The band gap is investigated based on the reflectance calculated by using the transfer matrix method. It is shown that, in the ultraviolet region, there is a photonic band gap which is strongly dependent on the loss and the incident angle for the transverse electric and transverse magnetic waves. Additionally, we find the photonic band gap can be significantly widened in a ternary semiconductor-metal-organic one. The effect of distinct metal on the band gap is also illustrated.
