Special Issue Information

Dear Colleagues,

In recent years, hollow-core fibers (HCFs) have emerged as a revolutionary technology, offering a myriad of unique properties such as low latency, low thermal sensitivity, reduced nonlinear effects, and potentially lower losses compared to solid-core fibers due to the fact that HCFs guide light in air/vacuum. In particular, following the groundbreaking achievement of low loss demonstrated by researchers at the University of Southampton (0.17 dB/km), HCFs have garnered significant attention and witnessed remarkable progress.

We are pleased to announce this Special Issue, titled "Recent Advances in Hollow-Core Fiber Optics: Design, Fabrication, and Applications", dedicated to exploring recent developments in HCFs across all aspects of research and development. We invite submissions of original research papers and review articles presenting state-of-the-art advancements, technical breakthroughs, experimental demonstrations, and practical applications. Topics of interest include, but are not limited to, the following:

  • Novel designs of HCFs;
  • Low-loss HCF fabrications across all wavelengths;
  • HCFs made of soft glasses and polymers;
  • Interconnection between HCFs and traditional solid-core fibers;
  • Characterization and properties of HCFs;
  • Hollow-core fiber-based components;
  • HCFs for high-power delivery systems;
  • Applications of HCFs in gas lasers and gas sensing;
  • Nonlinear effects in HCFs;
  • Microwave photonics utilizing HCFs;
  • HCFs in optical networks;
  • Emerging applications demonstrated with HCFs.

In this paper, a low loss and high polarization-maintaining single-mode hollow-core anti-resonant fiber (PM-HC-ARF) is designed. The elliptical core in the PM-HC-ARF is formed by strategically enlarging selected cladding air holes along the y-axis. Additionally, the variations in the wall thickness in both the x and y directions generate the distinct surface modes. By simultaneously employing an elliptical core and asymmetric core-wall thickness, we enhance the phase birefringence. Theoretical analysis results show that the proposed PM-HC-ARF achieves a transmission loss of 0.00082 dB/m at wavelength 1450 nm, along with a birefringence of 1.38 × 10−4; it demonstrates CL levels an order of magnitude below state-of-the-art polarization-maintaining HC-ARFs. Moreover, within the S+C+L+U communication bands, it achieves a bandwidth exceeding 380 nm (1420–1800 nm) while maintaining a birefringence of greater than 1.45 × 10−4. In particular, this PM-HC-ARF demonstrates a maximum higher-order mode extinction ratio of over 32,070; the single-mode transmission characteristics are excellent, along with exceptional bending resistance characteristics. When the bending radius exceeds 3 cm, the impacts on the loss and birefringence are negligible; this also demonstrates that the fiber structure shows good robustness when subjected to harsh environment interference. The proposed PM-HC-ARF is believed to have important applications in fiber optic gyroscopes, optical amplifiers, and hydrophones. Full article

This paper employs five different general-purpose optimization methods to perform parameter optimization on single-layer hollow antiresonant fibers. It provides guidance on the establishment of hyperparameters for various optimization methods, with the aim of further defining and standardizing the necessary conditions and convergence criteria for applying optimization algorithms to specialty optical fibers. Through numerical experiments, the study ultimately obtains the converged optimal performance and the range of optimized parameter guidance for single-layer, double-layer, and triple-layer antiresonant fibers with different topological structures.
