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

In the research field of hollow-core optical fiber (HCF), one type of fiber geometry with a
leaky mode nature has unexpectedly taken center stage over the last couple of years: the so …

Countering the optical network 'capacity crunch'calls for a radical development in optical
fibres that could simultaneously minimize nonlinearity penalties, chromatic dispersion and …

The optical performance characteristics of anti‐resonant hollow‐core fibers (known as AR‐
HCFs or ARFs) are improving rapidly, but the polarization maintaining issue with these fibers …

We systematically study different approaches to introduce high birefringence and high
polarization extinction ratio in hollow core antiresonant fibers. Having shown the …

A hollow-core anti-resonant fiber (HC-ARF) design based on hybrid silica/silicon cladding is
proposed for single-polarization, single-mode and high birefringence. We show that by …

Simple structures are always a pursuit but sometimes not easily attainable. It took
researchers nearly two decades for conceiving the structure of single-ring hollow-core …

We propose a polarization-filtering and polarization-maintaining negative curvature fiber in
which two nested resonant tubes are added to a standard negative curvature fiber with one …

UV guiding fibers are highly sought after in laser and spectroscopy applications. Recent
advances in hollow-core fiber orient a practical approach for proper UV light delivery …

The performance of optical fiber communication, laser, and sensing systems is ultimately
limited by the attenuation of optical fiber, which cannot be lower than the barrier set by …
