We demonstrate halving the record-low loss of interconnection between a nested
antiresonant nodeless type hollow-core fiber (NANF) and standard single-mode fiber (SMF) …

The elastic backscattering of light in optical fiber is a fundamental phenomenon that sets the
ultimate performance of several fiber systems such as gyroscopes and bidirectional transfer …

Hollow-core optical fibers (HCFs) have unique properties like low latency, negligible optical
nonlinearity, wide low-loss spectrum, up to 2100 nm, the ability to carry high power, and …

Negative curvature hollow-core fibers (NC-HCFs) can boost the excellent performance of
HCFs in terms of propagation loss, nonlinearity, and latency, while retaining large core and …

We theoretically explore the fundamental limits on the efficiency of coupling light into hollow-
core antiresonant fibres. We study in particular the coupling of a free-space Gaussian beam …

To go beyond the fundamental limits imposed by latency, nonlinearity, and laser damage
threshold in silica glass fibers, the hollow-core fiber (HCF) technique has been intensively …

The pervasive digital economy, fueled by developments in datacenter networking and
cloud/edge computing, relies ever increasingly on the implementation of short‐to metro …

The Fresnel reflection of a splice from the air–silica interface between a hollow-core fiber
(HCF) and a solid-core conventional fiber will increase the splicing loss and also cause …

We report simultaneous low coupling loss (below 0.2? dB at 1550? nm) and low back-
reflection (below− 60? dB in the 1200-1600? nm range) between a hollow core fiber and …

Optical detection of oxygen in A-band (near 13140 cm− 1 or 761 nm) with tunable laser
diode spectroscopy has been investigated and demonstrated in the past. However, as the …
