Hollow core photonic crystal fiber based viscometer with Raman spectroscopy [PDF]
, 2012 The velocity of a liquid flowing through the core of a hollow core photonic crystal fiber (driven by capillary forces) is used for the determination of a liquid's viscosity, using volumes of less than 10 nl.

Multimode Nested Antiresonant Hollow Core Fiber
Journal of Lightwave Technology, 2021 A novel centro-symmetric nested antiresonant fiber (CNAF) design is proposed and investigated numerically for low-loss, multimode applications. Conventional single tube-lattice and nested antiresonant hollow core fibers (ARHCFs) inherently support multiple core modes, but the higher order modes are more prone to coupling to lossy cladding modes ...

Modulational-instability-free pulse compression in anti-resonant hollow-core photonic crystal fiber
, 2020 Gas-filled hollow-core photonic crystal fiber (PCF) is used for efficient nonlinear temporal compression of femtosecond laser pulses, two main schemes being direct soliton-effect self-compression, and spectral broadening followed by phase compensation ...

Borosilicate Based Hollow-Core Optical Fibers [PDF]
Fibers, 2019 We discuss the fabrication of hollow-core optical fibers made of borosilicate glass. We show that, despite the high attenuation of the glass relative to silica, the fiber optical losses can be of the same order of magnitude of those obtained by using ultrapure silica glass.

Terahertz Hollow Core Antiresonant Fiber with Metamaterial Cladding
Fibers, 2020 A hollow core antiresonant photonic crystal fiber (HC-ARPCF) with metal inclusions is numerically analyzed for transmission of terahertz (THz) waves. The propagation of fundamental and higher order modes are investigated and the results are compared with

Connector-style hollow-core fiber interconnections
Optics Express, 2022 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 investigated for decades. Recent breakthroughs in ultralow-loss HCF clearly imply that long-haul applications of HCF in communications and lasers are going to appear ...

Feasibility of the optical fiber clock [PDF]
, 2017 We explore the feasibility of a compact high-precision Hg atomic clock based on a hollow core optical fiber. We evaluate the sensitivity of the $^1S_0$-$^3P_0$ clock transition in Hg and other divalent atoms to the fiber inner core surface at non-zero ...
