宽带吸收器由于其在实际应用中的广阔前景而备受关注。 该机制通常是几组具有不同几何尺寸的结构的叠加。 本文中，我们在数值上研究了基于多层相同尺寸的正方形板结构的，与现有的基于超材料的宽带太赫兹吸收器不同的方法。 在中心频率与1.96 THz相似的300 GHz频率范围内，可以获得大于99％的吸收。 该设备的FWHM最高可达到42％（相对于中心频率），是单层结构的2.6倍。 在很宽的入射角范围内都能很好地保持这种特性。 宽带吸收器的机理归因于层之间的纵向耦合。 设计的超材料吸收器的结果对于太阳能电池，检测和成像应用看来非常有希望。

Two-dimensional (2D) Te nanosheets were successfully fabricated through the liquid-phase exfoliation (LPE) method. The nonlinear optical properties of 2D Te nanosheets were studied by the open-aperture Z-scan technique. Furthermore, the continuous wave mode-locked Nd:YVO

We report Q-switched and mode-locked erbium-doped all-fiber lasers using ternary ReS2(1?x)Se2x as saturable absorbers (SAs). The modulation depth and saturable intensity of the film SA are 1.8% and 0.046 MW/cm2. In Q-switched mechanism output, the pulse was centered at 1531.1 nm with maximum pulse e

The expressions of pulse characteristics such as output energy, peak power, and pulse width are obtained by solving the coupled rate equations describing the operation of GaAs semiconductor saturable absorber Q-switched lasers. The key parameters of an optimally coupled GaAs saturable absorber Q-swi
