在这封信中，我们报告了一种基于太赫兹（THz）频率的平行板波导（PPWG）的宽带频率/偏振解复用器。该偏振敏感解复用器的制造和实验验证在 0.2 至 1 THz 范围内进行了演示。通过添加第二个解复用器级来升级解复用器，还在相同频率范围内演示了 550 幅度分配器。该多路复用器基于不锈钢行波天线，具有很强的机械鲁棒性。这种独特的设备在同一设备中表现出三种分裂机制：振幅、偏振和频率分裂。这对于用于通信目的的下一代太赫兹无源元件来说是一个重大改进。由光学协会根据知识共享署名 4.0 许可条款发布。
In this Letter, we report a broadband frequency/polarization demultiplexer based on parallel-plate waveguides (PPWGs) for terahertz (THz) frequencies. The fabrication and experimental validation of this polarization sensitive demultiplexer is demonstrated for the range from 0.2 to 1 THz. Upgrading the demultiplexer by adding a second demultiplexer stage, a fifty-fifty amplitude splitter is also demonstrated in the same frequency range. The multiplexer is based on a stainless-steel traveling-wave antenna, exhibiting strong mechanical robustness. This unique device exhibits three splitting mechanisms in the same device: amplitude, polarization, and frequency splitting. This is a significant improvement for the next generation of THz passive components for communication purposes.
