PWG1-XP, Ultra-High NA Select Cutoff SM Optical Fiber
Coherent extra high-performance Planar Waveguide Fiber provides a solution to the splicing challenges for high NA waveguiding structures. This fiber bridges high NA planar waveguides with low NA transmission fibers, achieving low splice loss and outstanding optical coupling.
Features and Benefits
- High numerical aperture - Bend insensitive 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
- Fibertails for planar waveguides
- Bridge fiber
- Silicon photonics devices
