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 …

Over the past few years, progress in hollow-core optical fiber technology has reduced the
attenuation of these fibers to levels comparable to those of all-solid silica-core single-mode …

High-power laser delivery with near-diffraction-limited beam quality is typically limited to tens
of metres distances by nonlinearity-induced spectral broadening inside the glass core of …

For over 50 years, pure or doped silica glass optical fibres have been an unrivalled platform
for the transmission of laser light and optical data at wavelengths from the visible to the near …

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 report broadband all-fiber optical phase modulation based on the photo-thermal effect in
a gas-filled hollow-core fiber. The phase modulation dynamics are studied by multi-physics …

Raman distributed optical fiber sensing is required to achieve accurate temperature
measurements in a micro-scale area. In this study, we first analyze and demonstrate the …

Abstract Hollow‐core fiber (HCF), in which> 99.99% of the light is guided in a central air (or
vacuum) filled core, is a radically new fiber technology offering the potential to overcome the …

Transparent silica glass is an indispensable material for today's information technology
society as an ultra-low loss optical fiber. Recently, further low-loss optical fibers are …
