摘要 为了研究利用新型器件提高辐射控制的能力,利用合成超构材料演示了一种太赫兹有源调制器的设计。该结构采用三维设计,除通过电压调节基底耗尽层载流子复合之外,还通过悬臂结构调节该结构的等效电磁参数,最终达到有效调节器件响应的目的。研究表明该器件能够实时、有效地对太赫兹辐射进行控制和操作。其对透射率的调制可达75%,频移0.1 THz,优于目前基于二维平面方法设计的太赫兹调制器件。 To improve the capability of radiation control with new devices,an active modulator at terahertz frequencies is designed with metamaterials.The structure under investigation is three dimensional.By adjusting the bias voltage applied on the substrate,the carrier recombination as well as the effective electromagnetic parameters are effectively altered,and the modulation of the structure is realized.The research shows that the modulator can control and operate THz radiation effectively and in real-time.The transmission modulation reaches 75% with the frequency shift more than 0.1 THz,which is better than that of structures with two dimensional designs,providing a novel way to construct new types of THz devices.
