摘要： In order to significantly improve the absorption efficiency of monolayer molybdenum disulfide (M-MoS2), an ultra-narrowband M-MoS2 metamaterial absorber was obtained through theoretical analysis and numerical calculation using the finite difference time domain method. The physical mechanism can be better analyzed through critical coupling and guided mode resonance. Its absorption rate at λ = 806.41 nm is as high as 99.8%, which is more than 12 times that of bare M-MoS2. From the simulation results, adjusting the geometric parameters of the structure can control the resonant wavelength range of the M-MoS2. In addition, we also found that the maximum quality factor is 1256.8. The numerical result shows that the design provides new possibilities for ultra-narrowband M-MoS2 perfect absorbers in the near-infrared spectrum. The results of this work indicate that the designed structure has excellent prospects for application in wavelength-selective photoluminescence and photodetection.
