The optical signal in a hollow-core photonic bandgap fibre is guided through an air core surrounded by a PBG microstructured region with a high air fill factor (>90%). Coupled with the low sensitivity to bending due to the high NA of the core, this gives this fibre design significantly reduced material non-linearities, since more than […]

The optical signal in a hollow core anti-resonant fibre propagates in an air core surrounded by a single ring of anti-resonant non-touching tubes. Guidance is based on an anti-resonant effect from the thin glass membranes of the tubes. The extremely low overlap of guided power with the surrounding silica, less than 2×10-5,added to the mode
