Special Issue Information

Dear Colleagues,

Photonic crystals (PCs) are periodic optical nanostructures that manipulate the flow of light by creating photonic bandgaps, enabling unprecedented control over electromagnetic waves. These materials have revolutionized photonics, offering applications in lasers, sensors, optical communications, and quantum technologies. By engineering their bandgap properties, PCs can confine, guide, or filter light at desired wavelengths, paving the way for next-generation optoelectronic devices. This Special Issue, “Advancements in Photonic Crystals: Materials, Design, and Applications”, seeks high-quality contributions on recent breakthroughs in PC research. Topics of interest include, but are not limited to, the following:

  • Fundamental physics of photonic crystals;
  • Novel materials for photonic crystals;
  • Advanced design and optimization methods for photonic crystals;
  • Theoretical and computational modeling of photonic band structures;
  • Photonic crystal devices and integrated photonics;
  • Biophotonics and medical applications;
  • Quantum and nonlinear photonic crystals.

In this paper, we design a new type of terahertz orbital angular momentum (OAM) optical fiber with excellent transmission characteristics over a wide frequency range. Within the 0.8–1.8 THz frequency band, it shows stable support for transmission of the fifth-order OAM mode. Its dispersion control effect is excellent; it maintains the confinement loss of most modes at the extremely low level of 10−10 dB/m; its maximum dispersion is only 5.57 ps/THz/cm; and its effective mode field area is greater than 1.11 × 10−7 m2. These characteristics jointly endow this optical fiber with broad application prospects and significant research value in the field of terahertz communication. With the continuous advancement of technology in this field, this optical fiber is expected to become a key component when building efficient, reliable, and large-capacity communication systems.
