Metamaterials have been widely applied in the polarization conversion of terahertz (THz) waves. However, common plasmonic metamaterials usually work as reflective devices and have low transmissions. All-dielectric metamaterials can overcome these sho

Metasurfaces are unique subwavelength geometries capable of engineering electromagnetic waves at will, delivering new opportunities for holography. Most previous meta-holograms, so-called phase-only meta-holograms, modulate only the amplitude distrib

Polarization, which represents the vector nature of electromagnetic waves, plays a fundamental role in optics. Fast, simple, and broadband polarization state characterization is required by applications such as polarization communication, polarimetry

Co3O4-cored carbon dots were prepared to induce chemiluminescence from the carbon dots in the presence of hydrogen peroxide at neutral pH. Neither a strong oxidative agent nor alkaline was needed as a co-reactant, which permitted for the first time t

In the terahertz regime, due to perfect conductivity of most metals, it is hard to realize a strong confinement of Surface plasmon polaritons (SPPs) although a propagation loss could be sufficiently low. We experimentally demonstrated a structure wit

We present an all-dielectric terahertz half-wave plate with an antireflection layer. The device is made of pure silicon, and can realize cross polarization conversion with almost 100% conversion rate and 90% of transmission at the operating frequency

We demonstrated a structure with periodic cylinders arranged bilaterally and a thin dielectric layer covered inside that supports bound modes of surface plasmon polaritons at terahertz frequencies. This structure can confine the surface plasmon polar
