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

High-performance interferometers, gyroscopes, frequency combs, quantum information
experiments and optical clocks rely on the transmission of light beams with the highest …

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 …

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 …

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 …

A novel single-polarization single-mode double-ring hollow-core anti-resonant fiber with two
single-polarization regions (1545–1553 nm and 1591–1596 nm) is proposed. Single …

Hollow-core fibers have demonstrated record performance in applications such as high-
power pulse delivery, quantum computing, and sensing. However, their routine use is yet to …

A novel high-birefringence hollow-core anti-resonant THz fiber is proposed in this paper.
This fiber has a simple structure which consists of only ten Topas tubes. High birefringence …

We present a novel hollow-core anti-resonant optical fiber (ARF) with nested elliptical and
nested circular air holes, where these cladding air holes form into the elliptical core. The …
