We proposed to design a tunable multichannel optical filter composed of uniaxial indefinite metamaterial and dielectric photonic crystal categories arrangement, which can be employed as a valuable variation of peak transmission in microwave frequency. Because of the optical axis and polarization dependence of the uniaxial metamaterial layer, the position trend in the multichannel optical filter is shown to also rely on both TE and TM polarizations. The numerical results show that by changes of the incidence angle, width of photonic band gap (PBG) compacts (widens) at TE (TM) polarization and the PBG of the structure shifts towards the higher frequency region, for both polarizations. In addition, the multichannel optical filter properties and shift trend of the PBG are also affected by changing the optical axis of the uniaxial indefinite metamaterial. Thus, results shown that without appending defect layer in this structure, the sets of comb-like resonant peaks in transmission modes can be utilized in the lower or higher band edge of PBG at TE and TM polarizations.
