Special Issue Information
Dear Colleagues,
Hollow-core optical fibers (HCFs) have witnessed remarkable advancements in recent years, achieving unprecedented milestones in broadband, low-loss, and low-latency transmission. These achievements extend well beyond telecommunications, with HCFs enabling transformative applications in diverse fields, including nonlinear optics in gas- and liquid-filled fibers, high-sensitivity sensing, spectroscopy, fiber lasers, biomedical diagnostics, optofluidics, and quantum technologies.
The field has delivered impressive results—such as sub-cycle and sub-femtosecond optical pulse compression, the millijoule-level energy scaling of optical solitons, and the generation of multi-octave Raman frequency combs—and continues to expand. HCFs have also paved the way for a new class of gas-based light sources spanning the deep ultraviolet to the mid-infrared. These fibers offer incredible potential for nonlinearity-free laser beam delivery, with demonstrations of the high-beam-quality transmission of kilowatt-level continuous-wave lasers and gigawatt-peak-power ultrashort pulses.
This Special Issue invites original research articles showcasing the latest theoretical, numerical, and experimental advances in hollow-core optical fibers and their wide-ranging applications. Topics include, but are not limited to, the following:
- Novel optical fiber geometry design, fabrication, and characterization;
- Hollow-core fibers for telecommunications;
- Multimode hollow-core fibers and their applications
- The spectroscopy and sensing applications of hollow-core fibers;
- Ultrafast optics in hollow-core fibers;
- Light–matter interactions in hollow-core fibers;
- Deep-UV sources using hollow-core fibers and their applications;
- Mid-IR sources using hollow-core fibers and their applications;
- Laser beam delivery using hollow-core fibers;
- Interconnections of hollow-core fibers with all-solid fibers;
- Hollow-core fiber-based inline devices;
