Wideband low confinement loss anti-resonant hollow core fiber with nested U-shape tube.

open access: yesOptics Express, 2021
We propose a nested U-shape tube anti-resonant hollow core fiber (UARF) that can effectively reduce the confinement loss (CL) as well as the loss oscillations. The key parameters of UARF have been optimized via numerical analysis. Simulation results show

Sodium-Based Cylindrical Plasmonic Waveguides in the Near-Infrared

open access: yesNanomaterials, 2022
Subwavelength optical field confinement and low-loss propagation are of great significance for compact photonic integration. However, the field confinement capability of plasmonic devices is always accompanied by the inherent Ohmic loss.

Confinement loss of anti-resonant capillaries with curved boundaries

open access: yesOptics Express, 2021
A systematic analysis of the dependence of the confinement loss of an anti-resonant capillary on the curvature of the core surround is presented. The core boundary is described by circular arcs and the construction allows for a wide range of core shapes to be considered.

Sensitivity of confinement losses in optical fibers to modeling approach

open access: yesOptics Express, 2023
A prime objective of modeling optical fibers is capturing mode confinement losses correctly. This paper demonstrates that specific modeling choices, especially regarding the outer fiber cladding regions and the placement of the computational boundary, have significant impacts on the calculated mode losses.
