We present a broadband terahertz (THz) polarizer based on the stacks of aligned Ni nanowire (NW) arrays. We demonstrated that the polarizer has an extinction ratio of 58.8 dB and an average extinction ratio of 46.6 dB throughout a frequency range of 0.3-2.3 THz. Compared to carbon-nanotube and metallic wire-grid polarizers, our Ni-NW polarizers with rapid, reliable, low-cost fabrication processes are ideal candidates for emerging THz technologies.
我们展示了一种基于对齐的镍纳米线（NW）阵列堆叠的宽带太赫兹（THz）偏振器。我们证明，该偏振器在0.3 - 2.3太赫兹的频率范围内，消光比为58.8分贝，平均消光比为46.6分贝。与碳纳米管和金属线栅偏振器相比，我们的镍纳米线偏振器具有快速、可靠、低成本的制造工艺，是新兴太赫兹技术的理想候选者。
