IEEE Access, 2020 We report on a novel weakly-coupled 6-LP-mode fiber that features a nanopore-assisted step-index core with double-cladding profile. The purpose of this fiber design is to alleviate modes coupling and bend sensitivity, thus simplifies the multiple-input ...

Resonant bend loss in leakage channel fibers [PDF]
Optics Letters, 2012 Leakage channel fibers, designed to suppress higher-order modes, demonstrate resonant power loss at certain critical radii of curvature. Outside the resonance, the power recovers to the levels offset by the usual mechanism of bend-induced loss. Using C$^2$-imaging, we experimentally characterize this anomaly and identify the corresponding physical ...

Low loss modified Bezier bend waveguide
Optics Express, 2022 We proposed and experimentally demonstrated a low loss modified Bezier bend for silicon and silicon nitride photonic integrated circuits. Both simulation and experimental results confirm that the modified Bezier bend can effectively reduce the bend loss for silicon and silicon nitride platform.

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 ...

Crystals, 2023 In this paper, a low-loss 90°-bending design in femtosecond laser-induced double-line waveguides is theoretically proposed and experimentally demonstrated. The bending is realized based on the total internal reflection of a corner mirror (made by precise

Bend loss in structured optical fibres
Optics Express, 2007 Bend loss characterisation tests are carried out in two air-silica structured fibres: a periodic photonic crystal fibre and a non-periodic fibre. An explanation based on resonant coupling between interstitial zones accounts for the improved confinement of non-periodic structured optical fibres.
