A defective Thue–Morse quasi-photonic crystal containing molybdenum disulfide (MoS2) is suggested to construct an ultra-narrowband multiple resonant absorber in the visible range. Multiple high absorption peaks can be achieved by altering the design of the proposed structure in different ways such as changing the generation number or the symmetry with respect to defect. Two structures are introduced, which create more than seven absorption peaks higher than 40% and one of the peaks about 100%. Defect modes' wavelength can be tuned to show the blue shift by incident angles and the polarization of light. Our optimal structures are useful for applications in multiplex filters and multiple channel sensors due to their high amount and narrowband absorption peaks and can show nearly perfect absorption.
