High-power single-frequency fiber lasers with exceptional properties, such as mode-hop-
free and narrower linewidths, lower noise, and compact all-fiber designs, have been …

We describe the history, guiding mechanism, recent advances, applications, and future
prospects for hollow-core negative curvature fibers. We first review one-dimensional slab …

Since their inception, about 20 years ago, hollow-core photonic crystal fiber and its gas-filled
form are now establishing themselves both as a platform in advancing our knowledge on …

The field of hybrid optical fibers is one of the most active research areas in current fiber
optics and has the vision of integrating sophisticated materials inside fibers, which are not …

Fibre lasers operating at the mid-IR have attracted enormous interest due to the plethora of
applications in defence, security, medicine, and so on. However, no continuous-wave (CW) …

We first use numerical simulations to show that bending losses of hollow antiresonant fibers
are a strong function of their geometrical structure. We then demonstrate this by fabricating a …

Mid-infrared (IR) lasers are currently an area of rapid development, with several competing
technologies. In traditional gas lasers, the effective interaction length is limited and the …

After decades of research, there are almost half a dozen efficiently pumped rare earth laser
transitions in a fiber laser format capable of Watt-level output. These systems use near-IR …

We report on numerical and experimental studies showing the influence of arc curvature on
the confinement loss in hypocycloid-core Kagome hollow-core photonic crystal fiber. The …
