Fibre cœur creux anti-résonnant
Optical signal in a hollow core anti-resonant fibre 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.
Main characteristics :
- High damage threshold
- Nearly single mode guidance
- Ultra low dispersion in the transmission bands
Applications :
- 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

Fibre cœur creux Photonic Bandgap
Optical signal in a hollow core photonic bandgap fibre is guided in an air core surrounded by a high air filling factor PBG microstructured region (>90%). Added to the low bend sensitivity due to the core high NA, this confers to this fibre design significantly reduced material nonlinearities since more than 95% of optical power is propagating in air. In addition air/undoped silica provides excellent temperature immunity critical for high performance fibre sensing and metrology applications.
Main characteristics :
- Air core, ultra-low nonlinear coefficient
- Low background losses
- Low dispersion in the centre of the transmission band
Applications :
- Power delivery
- Fibre sensors
- Nonlinear applications (pulse compression, shaping)
