通过采用亚波长介质光栅激发一维光子晶体(1DPC)的导模谐振,在数值上提出了具有超窄带宽的石墨烯完美吸收体。 1DPC 导模共振与石墨烯的临界耦合可以产生具有 0.03nm 超窄带宽的完美吸收。吸收峰的品质因数达到20000的超高值。还发现可以通过控制导模色散线和光栅周期来调谐谐振吸收峰。当光栅和 1DPC 的参数设置适当时,可以将完美的吸收峰调谐到可见光波长范围内任意随机选择的波长。
Graphene perfect absorbers with ultranarrow bandwidth are numerically proposed by employing a subwavelength dielectric grating to excite the guided-mode resonance of one-dimensional photonic crystals (1DPCs). Critical coupling of the guided-mode resonance of 1DPCs to graphene can produce perfect absorption with a ultranarrow bandwidth of 0.03 nm. The quality factor of the absorption peak reaches a ultrahigh value of 20000. It is also found that the resonant absorption peaks can be tuned by controlling the dispersion line of the guided mode and the period of the grating. When the parameters of the grating and the 1DPCs are suitably set, the perfect absorption peaks can be tuned to any randomly chosen wavelength in the visible wavelength range.
