As more than 98% of the mode is confined in air, the fibers are also very radiation insensitive making them suitable for radiation hard environments.
- High threshold power for non-linear effects
- Pure silica material
- The core can be filled with gasses, particles, etc.
- Extreme dispersion values for pulse compression/dispersion compensation
- No Fresnel reflections at open fiber ends
Other advantages with these fibers are that they are almost entirely bend-insensitive. They can be bent down to a bend diameter <1 cm without any change in the optical transmission.
