Hollow core photonic bandgap fibers for telecommunications: opportunities and potential issues [PDF]

, 2012
We discuss the potential advantages that hollow core photonic bandgap fibers may ultimately have over conventional all solid fibers and review the state-of-the-art, fundamental physical limits and the many technological challenges to be ...

Hollow core fiber with an octave spanning bandgap [PDF]

, 2010
We thoroughly compare the out-of-plane bandgaps generated by three realistic two-dimensional lattices: a triangular and a square arrangement of holes and a triangular arrangement of rods.

Optimising the performances of hollow antiresonant fibres [PDF]

, 2011
We study the loss of novel antiresonant hollow-core fibres, demonstrate the existence of a wavelength independent optimum distance between core-surround and solid outer cladding, and provide useful guidelines for the fabrication of practical low-loss ...

Direct Laser Writing of SERS Hollow Fibers

Nanomaterials, 2022
We report the direct laser writing (DLW) of surface-enhanced Raman scattering (SERS) structures on the inner wall of a hollow fiber. Colloidal gold–silver alloy nanoparticles (Au–Ag ANPs) are firstly coated onto the inner wall of a hollow fiber.
