Wavelength-division multiplexing (WDM) has historically enabled the increase in the
capacity of optical systems by progressively populating the existing optical bandwidth of …

The loss of hollow-core Nested Antiresonant Nodeless Fiber (NANF) has been steadily
decreasing lately, approaching that of standard Single-Mode Fiber (SMF). As for non-linear …

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 …

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

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

Remarkable recent demonstrations of ultra-low-loss inhibited-coupling (IC) hollow-core
photonic-crystal fibres (HCPCFs) established them as serious candidates for next …

Dual-comb spectroscopy (DCS) has revolutionized optical spectroscopy by providing
broadband spectral measurements with unprecedented resolution and fast response …
