摘要

利用蚀刻有周期性分布矩形孔的硅衬底构建了一个多功能太赫兹元件（MTE），该元件集成了四分之一波板、半波板和反射器的功能。结果表明，在超过 1 太赫兹的带宽内，四分之一波板的透射率超过 90%；在 5 太赫兹时，半波板的偏振转换效率接近 100%；在 13 太赫兹至 21 太赫兹的频率范围内，反射器的反射率保持 100%。它适用于光子芯片集成，以实现偏振控制和滤波，在传感、检测和光子计算领域有着广泛的应用。

Terahertz multifunctional elements based on all-dielectric metamaterials

A multifunctional terahertz element (MTE) was constructed with a silicon substrate etched with periodically distributed rectangular holes, integrating the functions of a quarter-wave plate, half-wave plate, and reflector. Results show that the quarter-wave plate has a transmittance of over 90 % within a bandwidth exceeding 1 THz, the half-wave plate achieves nearly 100 % polarization conversion efficiency at 5 THz, and the reflector maintains 100 % reflectivity within the frequency range of 13 THz to 21 THz. It suitable for photonic chip integration to achieve polarization control and filtering, with broad applications in sensing, detection, and photonic computing.
