Summary:We investigated the transmittance properties of the one dimensional quasiperiodic photonic crystals that contains an n doped semiconductor material. Our study is mainly based on the theoretical framework of the plasma model and the characteristic matrix method. Here, Fibonacci sequence represents the core axis in the design of our structure. Therefore, this design could be named as Fibonacci based structure. The numerical results are mainly based on the variation of the doping concentration. This parameter could be crucial in the tunability of the photonic band gaps. The effect of many parameters such as the thickness of the semiconductor material, the sequence number and the type of the sequence are demonstrated. The designed structure is prepared to act as a multichannel filter for THz applications.
