Special Issue Information

Dear Colleagues,

Rare-earth-doped micro-/nano-crystals and other atoms are widely used in quantum information, super-resolution imaging, and biofluorescent labeling due to their stable luminescence, rich wavelength, narrow linewidth, and long life. The interaction between coherent light and their atom-like structure provides a feasible method for generating quantum-like states of photons. Moreover, spontaneous four-wave mixing based on their atom-like composition presents the following advantages: narrow spectral linewidth, long coherence time, large phase mismatch range, multiple spatial modes, high signal brightness, and high signal-to-noise ratio. Therefore, these atoms have valuable applications in the fields of long-distance quasi-quasi-secure communication and quatern-like memory. Nevertheless, nonlinear optical phenomena in rare-earth-doped crystals face many challenges regarding novel applications.

In this Special Issue, original research articles and reviews are welcome, with research areas encompassing the following:

  • Nonlinear optics;
  • Quantum optics;
  • Rare-earth-doped crystals;
  • Luminous micro-/nano-materials;
  • Rare-earth-doped single-particle crystals;
  • Photonics;
  • Information optics;
  • Nonlinear quantum optics;
  • The interaction between lasers and matter;
  • Pulsed lasers.

We look forward to receiving your contributions.

The ultra-wideband polarization converters have been of interest to researcher due to their demand in satellite communication and navigation systems. This paper presents an ultra-wideband reflective cross-polarization converter comprising a stair-shaped metasurface. By observation, the alleged structure allows the conversion of linearly polarized waves to orthogonal components, having a polarization conversion ratio of greater than 90% spread across the large frequency range of 12.94 to 16.54 GHz and 17.54 to 26 GHz. A highly efficient, ultra-high frequency polarization conversion is achieved by the utilization of strong electromagnetic resonance coupling between the upper and lower layers of the metasurface. Further, it is depicted that the polarization converter has a wide obliquity of incidence wave. Moreover, the simulation and measured results show a good match. The linear polarization converter is simple in design but is of high performance, and therefore, might be useful in satellite communication, imaging systems, and navigation systems. Full article
