Hollow-Core Anti-Resonant Fiber

Hollow-Core Anti-Resonant Fiber

Lumentum Advanced Specialty Optical Fiber Family

Lumentum’s Hollow-Core Anti-Resonant Fibers (HC-ARFs) are engineered for high-power laser transmission featuring high threshold for non-linear effects, exceptional beam quality, and low dispersion. Designed for consistent fundamental-mode operation, HC-ARFs offer stable, high-quality beam transmission across a broad spectral range.

Manufacturing of hollow core fibers is done under stringent process control standards, ensuring reproducible fiber structure and comprehensive traceability. Lumentum offers technical support from initial design through final integration to optimize application-specific fiber performance.


Typical Applications


HC-ARFs are ideally suited for ultrafast laser beam delivery, precision spectroscopy, nonlinear optics experiments, medical laser delivery, advanced sensing systems, and specialized communications requiring high-power handling, low nonlinearities, and consistent beam quality.

Hollow-Core Anti-Resonant Fiber

Key Features

 

  • Ultra-Low Nonlinearity: Hollow-core structure minimizes interaction between light and fiberglass, reducing nonlinear effects such as SRS (Stimulated Raman Scattering) and SPM (Self-Phase Modulation)
  • High Damage Threshold: Air-core structure supports high-intensity picosecond and femtosecond laser pulses without material degradation, with the possibility of vacuum or gas filling to further enhance damage and non-linear effects thresholds
  • Higher-Order Mode Suppression: Precisely engineered core geometry ensures stable fundamental-mode operation and superior beam quality
  • Broad Spectral Transmission: Wide spectral windows across visible and near-infrared ranges, providing flexibility for multiwavelength applications
  • Controlled Dispersion: Tailorable dispersion characteristics can be achieved by customizing core dimensions, wall thickness, and optional gas fills for pulse preservation and compression 
  • Bend Tolerance: Fibers are optimized for low bending sensitivity, improving versatility of operation
  • Documented consistency: Each reel includes a measurement summary, streamlining incoming inspection and system qualification
  • Expert Application Support: Engineering assistance available throughout the design, modelling, integration, and qualification processes
