Optical Properties of a Periodic One-Dimensional Semiconductor-Organic Photonic Crystal

Abstract
Theoretical calculations via the transfer matrix method (TMM) are performed to investigate optical properties of one-dimensional semiconductor-organic photonic crystals (SOPC) with periodic conjugated polymer (3-octylthiophenes,P3OT)/AlN multilayer structure.The SOPC presents incomplete photonic band gap behavior in the UV region.P3OT/AlN multilayers with two pairs of 30nm-P3OT and 30nm-AlN layers exhibit a photonic band gap at a central wavelength of about 275nm,and the highest reflectivity reaches 98%.Furthermore,the band gaps are confirmed to be tunable by adjusting the lattice period and the filling fraction.As a consequence,the SOPC is important for achieving materials with an incomplete band gap in the UV region.-
