Enhanced entangled photon-pair generation rate with dual quasi-bound states in the continuum metasurfaces

C. L. Zhong, Wei Zou, Tianjing Guo, Christos Argyropoulos

Spontaneous parametric down-conversion (SPDC) is a fundamental quantum optical technique for generating entangled photon pairs, which serves as the foundation for various quantum applications, including quantum cryptography, quantum simulation, quantum metrology, and the exploration of fundamental physical laws in quantum mechanics. Nevertheless, …

Engineered Graphene Nanostructures and Their Applications in the Terahertz Regime

Christos Argyropoulos, Tianjing Guo

Graphene is a monolayer of carbon atoms constructing a two-dimensional (2D) honeycomb lattice that has two sp2-bonded atoms in the primitive unit cell. It was first isolated in its planar form using adhesive tape in 2004 by a group of scientists at …

Robust multimode interference and conversion in topological unidirectional surface magnetoplasmons

Chao‐Xing Liu, Ziyang Zhao, Tianjing Guo, Jie Xu et autres

We have theoretically investigated surface magnetoplasmons (SMPs) in an yttrium-iron-garnet (YIG) sandwiched waveguide. The dispersion demonstrated that this waveguide can support topological unidirectional SMPs. Based on unidirectional SMPs, magnetically controllable multimode interference (MMI) is verified in both symmetric and asymmetric waveguides. Due …

Multiple truly topological unidirectional surface magnetoplasmons at terahertz frequencies

Shuting Fan, Tianjing Guo, Binbin Zhou, Jie Xu et autres

Unidirectional propagation based on surface magnetoplasmons (SMPs) has recently been realized at the interface of magnetized semiconductors. However, usually SMPs lose their unidirectionality due to non-local effects, especially in the lower trivial bandgap of such structures. More recently, a truly unidirectional SMP …

Broken phase of parity-time symmetry enables efficient superluminal pulse transmission

Liting Wu, Ming Kang, Tianjing Guo, Jing Chen

Parity-time ( P T ) symmetric Bragg gratings (PTBGs) exhibit unique band characteristics compared to their traditional counterparts. Notably, when the P T symmetry is broken, the initial bandgap closes, and the upper and lower branches coalesce. We demonstrate that this believed …

Design, simulation, and experimental realization of a high-sensitivity polarization-independent electromagnetically induced transparent terahertz metamaterials

Xinwei Zhou, Le Li, Yun Shen, Lujun Hong et autres

Electromagnetically induced transparency (EIT) originating from quantum physics can lead to a very narrow-band transparent window, which is sensitive to minor environmental changes. The rational construction of highly sensitive EIT metamaterials facilitates its wide sensing application in the terahertz (THz) range. In …

Ultrabroadband coherent perfect absorption with composite graphene metasurfaces

Wei Zou, Tianjing Guo, Christos Argyropoulos

We investigate the design and performance of a new multilayer graphene metasurface for achieving ultrabroadband coherent perfect absorption (CPA) in the THz regime. The proposed structure comprises three graphene patterned metasurfaces separated by thin dielectric spacer layers. The top and bottom metasurfaces …
