UHNA1, Ultra-High NA Select Cutoff SM, Optical Fiber
Coherent Ultra-High NA fibers are part of the NuBRIDGE Fluoroacrylate fiber family and 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.
Features
- 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
- RoHS compliant
Applications
- Fluoride and other non-silica fibers
- Planar Waveguides
- Silicon photonics devices
- Fiber tails for high NA sources
- Bridge Fiber
