Anti-resonant hollow core fibre
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.
- High damage threshold
- 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
Low latency anti-resonant hollow-core cable
Photonics Bretagne and IDIL launch a new range of anti-resonant Hollow-core fiber optic cables. They combine low latency data transmission, high bandwidth connections and low loss; three features highly sought after by high frequency trading.
“We are proud to be at the forefront of this technological breakthrough where each nanosecond counts” said David MECHIN from Photonics Bretagne.
“Low latency cables are fully compatible and deployable in existing communication networks. These indoor/outdoor cables are easy to integrate and customizable. Customers can choose the length, number of fibers, connectors” said Boris PEDRONO from IDIL.
Hollow Core Photonic Bandgap Fibre
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.
- Air core, ultra-low nonlinear coefficient
- Low background losses
- Low dispersion in the centre of the transmission band
- Power delivery
- Fibre sensors
- Nonlinear applications (pulse compression, shaping)
