Anti-resonant hollow core fibers
Photonic crystal & multicore fibers
Optical signal in a hollow core anti-resonant fiber propagates in an air core surrounded by single ring of anti-resonant tube elements.
Optical signal in a hollow core anti-resonant fiber propagates in an air core surrounded by single ring of anti-resonant tube elements. Guidance is based on an anti-resonance from the thin glass membranes constituted by the non-touching tubes surrounding the hollow core. The extremely low overlap of guided power with the surrounding silica, less than 2×10 -5, added to the mode effective area, confers to this fibre design record material non-linearity.
Features

- Nearly single mode guidance
- Ultra low dispersion in the transmission bands
- Low latency data transmission
- Gas-filled AR hollow core fibre laser
- Molecular tracing, gas detection
- High-power delivery for pico- and sub-picoseconds optical pulses
