摘要
我们提出了一种由石墨烯和黑磷(G-BP)组成的新型光子器件,它在太赫兹范围内实现了高性能的等离子体诱导透明(PIT)效应,并保持了很好的可调性和各向异性。PIT 效应的各向异性源于两个亮模式之间的近场耦合,这两个亮模式的特征是 BP 具有不同的有效电子质量,从而导致透明窗口在 TE 极化时为 33.35 THz,在 TM 极化时为 26.92 THz。通过分别调节石墨烯的费米能、BP 的掺杂水平和几何参数,实现了可调的透明窗口。值得注意的是,各向异性透明度窗口的收敛或发散可以通过不同的 BP 掺杂水平进行良好的操控。此外,所提出的 G-BP 光子器件对周围折射率和基底的变化具有很高的灵敏度,最大灵敏度为 12.04 THz/RI,因此适合传感器应用。总之,所提出的光子器件表现出显著的 PIT 效应,具有各向异性能高、可调性强、灵敏度高和稳定性好等特点,因此有望应用于传感器、偏振器和开关等领域。
Tunable plasmon-induced transparency in anisotropic graphene-black phosphorus photonic device for high-performance sensors and switchers
A novel photonic device composed of graphene and black phosphorus (G-BP) has been proposed, which achieves high-performance plasmon-induced transparency (PIT) effect within the THz range and maintains substantial tunability and anisotropy. The anisotropy of the PIT effect arises from the near-field coupling between two bright modes characterized by distinct effective electron masses of BP, resulting transparency window at 33.35 THz for TE polarization and at 26.92 THz for TM polarization. Through the modulation of Fermi energy in graphene, doping levels of BP and geometric parameters separately, a tunable transparency window is achieved. Notably, the convergence or divergence of the anisotropic transparency windows can be well manipulated with different BP doping levels. Furthermore, the proposed G-BP photonic device exhibits a high sensitivity to changes in the surrounding refractive index and substrates, with a maximum sensitivity of 12.04 THz/RI, rendering it suitable for sensor applications. Overall, the proposed photonic device exhibits notable PIT effects characterized by high anisotropic performance, substantial tunability, great sensitivity, and stability, making it a promising candidate for applications in sensors, polarizers, and switchers.
