Product Overview


PFP Ultra-High NA fibers are excellent bridge fibers between high NA waveguides and low NA transmission fiber. Ultra-High NA fibers provide excellent coupling efficiencies to high NA waveguides. In addition, the composition of Ultra-High NA fibers are tailored to thermally expand the core during splicing thus achieving lower splice loss to transmission fiber.
  • Fluoride and other non-silica fibers
  • Planar Waveguides
  • Fiber tails for high NA sources
Features & Benefits
  • High numerical aperture - Bend insensitive fiber for miniature packages
  • Thermally expandable core - Low splice loss to transmission fiber
  • Small Mode Field Diameter - High coupling efficiency with Planar Waveguides
