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 …

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 …

Laser spectroscopy outperforms electrochemical and semiconductor gas sensors in
selectivity and environmental survivability. However, the performance of the state-of-the-art …

Photonic technologies offer numerous functionalities that can be used to realize
astrophotonic instruments. The most spectacular example to date is the ESO Gravity …

While optical fibers display excellent performances in the infrared, visible and ultraviolet
ranges remain poorly addressed by them. Obtaining better fibers for the short-wavelength …

We study the mid-infrared attenuation of antiresonant hollow-core fiber made of fused silica
glass. The role of absorptive losses increases with wavelength but can be minimized by …

Revolver optical fibers (RF) are special type of hollow-core optical fibers with negative
curvature of the core-cladding boundary and with cladding that is formed by a one ring layer …

Exosome-based liquid biopsies highlight potential utility in diagnosis and determining the
prognosis of patients with cancer and other diseases. However, the existing techniques are …

In this paper, we report the use of a 3-meter low-loss anti-resonant hollow-core fiber (AR-
HCF) to deliver up to 300 W continuous-wave laser power at 1080 nm wavelength from a …

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 …
