[0024] Example 1
[0025] Such as figure 1 , figure 2 with image 3 As shown, this embodiment provides a near-infrared waveband linear thermo-optical tunable ultra-narrowband absorber based on four-nanometer column coupled vibrator. The absorber includes a plurality of periodic structural units, and each periodic structural unit is three Layer structure, the bottom layer is a gold film, the middle layer is a silicon nitride film, the top layer is a vibrator formed by coupling four nano-pillars, and the material of the vibrator is amorphous silicon material (also called four-nanometer-pillar coupled amorphous silicon vibrator). In this embodiment, the four nanopillars are arranged and coupled in a 2×2 manner, and the four nanopillars are all rectangular parallelepipeds, and the upper and lower bottom surfaces are square. Specifically, the following parameters are used: the thickness of the gold film at the bottom layer is T3=200nm, the thickness of the silicon nitride dielectric ...
