We review the topic, focusing first on a discussion of the key parameters, limits of coupling loss, and measurement techniques. We then follow by reviewing the literature, including mode-field adaptat...

Abstract An optical fiber Fabry-Perot sensor to monitor the solid-liquid and liquid-solid phase changes in n-octadecane is investigated. The sensor probe is fabricated by splicing a short
We characterized the transmission of UV laser light through a single-ring hollow-core optical fiber which is designed for low-loss, single-mode transmission over a wavelength range of 250 nm to 450 nm.
Multimode optical fibers have various applications in many fields, including high-power laser delivery, short-haul telecommunications and sensing, etc. Hollow-core anti-resonant fiber (HC
Debugging a simple single-mode fiber connection problem After lots of experience with wired and wireless networks, I''ve recently started to play with some basic fiber equipment. To that end I''ve
Abstract 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).
High-performance interconnection between hollow-core fiber and conventional solid-core fiber is of great significance for a lot of promising applications of hollow-core fibers. The current problems for high
We observe typical fiber modes in the k-space and clarify differences of their momentum characteristics, based on which a mode selection principle is proposed. As a theoretical proof of the
We demonstrate the first measured hollow-core fiber employing Perturbed Resonance for Improved Single Modedness (PRISM). The fiber has fundamental-mode loss of 7.5 dB/km, while
The flexible delivery of UV-visible light is vital for many applications. Here we report the development of a new fabrication approach that allows broadband UV-visible guiding hollow-core fibers, with
We study fusion splicing of anti-resonant hollow-core fiber with low loss (0.52 dB) and conventional single-mode fiber using a convenient graded-index bridge fiber.
Abstract: A novel microfiber sensor is proposed and demonstrated based on a singlemode-tapered hollow core-singlemode (STHS) fiber structure. Experimentally a STHS with taper waist diameter of
An example of such a structure is the Kagome type´ . Recently, single-ring structures formed by capillaries surrounding the hollow-core have gained increasing interest because of both low-loss
When there are no metal wires, the hollow core anti-resonant fiber has a broadband single mode property by adjusting structure parameters. Then, through embedding two symmetrical metal
A hybrid microstructured cladding significantly reduces confinement loss and preserves single-mode operation in hollow-core photonic crystal fibres. The hybrid cladding was conceptualised
We report the optimization of hollow-core anti-resonant fibers incorporating elliptical tubes to maximize higher order mode extinction ratio (HOMER), with a small penalty on confinement loss of
The difficulty of fusion splicing hollow-core photonic bandgap fiber (PBGF) to conventional step index single mode fiber (SMF) has severely limited the implementation of PBGFs.
Abstract—We propose an approach to interconnect a hollow- core fiber (HCF) of arbitrary core size with standard single-mode fiber with perfect mode-field size adaptation and experimentally achieve for the
Introducing stress in the core (the dominant method of making conventional, solid polarization-maintaining (PM) fibres) is clearly not possible in a hollow fibre.
