Optical signals in a hollow core photonic bandgap fiber are guided in an air core surrounded by a PBG microstructured region. In addition to the low bend sensitivity, this fiber design exhibits significantly reduced material nonlinearities since more than 95% of optical power is propagating in air. In addition, air/undoped silica provides excellent temperature immunity, which is critical for high performance fiber sensing and metrology applications.

Optical signals in a hollow core anti-resonant fiber propagate in an air core surrounded by a 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, in addition to the large effective mode area, leads to a record-low optical nonlinearity.
