Photonic crystal fibres: mapping Maxwell’s equations onto a Schrödinger equation eigenvalue problem [PDF]
Journal of the European Optical Society-Rapid Publications, 2006 We consider photonic crystal fibres (PCFs) made from arbitrary base materials and introduce a short-wavelength approximation which allows for a mapping of the Maxwell’s equations onto a dimensionless eigenvalue equations which has the form of the ...

Investigation of a Large-Mode-Area Fiber Designed for 2.0 μm Based on Multi-Layer Holes Resonance
IEEE Photonics Journal, 2023 This work proposes a novel large mode area fiber with multi-layer holes of 2.0 μm based on electromagnetic field theory and finite element analysis. Modifying the structure parameters can reduce the fundamental mode confinement loss to less than 0.

Influence of Pedestal Fiber Splice on Tm-Doped Fiber Laser Performance
IEEE Photonics Journal, 2023 The influence of Tm-doped pedestal fiber splice on the output performance of a large-mode-area (LMA) Tm-doped fiber laser (TDFL) has been investigated. Arc-fusion induced refractive-index deformation leads to laser leakage from the core to the pedestal ...
