“…Hollow-core photonic bandgap fibers (HC-PBGFs) [4,5] proved to be able to guide light in air with attenuation as low as 1.2 dB∕km at 1.62 μm wavelength [6]. Another type of hollowcore fiber known as "Kagomé" fiber [7] has also been developed for its particular characteristic of combining relatively low attenuation with broad bandwidth [8]. Although it does not possess a photonic bandgap cladding, it guides light with reduced leakage compared to a standard capillary because of the presence of an antiresonant glass layer [9,10] surrounding the air core.…”

An improved design for hollow antiresonant fibers (HAFs) is presented. It consists of adding extra antiresonant glass elements within the air cladding region of an antiresonant hollow-core fiber. We use numerical simulations to compare fiber structures with and without the additional cladding elements in the near- and mid-IR regimes. We show that realizable fiber structures can provide greatly improved performance in terms of leakage and bending losses compared to previously reported antiresonant fibers. At mid-IR wavelengths, the adoption of this novel fiber design will lead to HAFs with reduced bending losses. In the near-IR, this design could lead to the fabrication of HAFs with very low attenuation.

“…Benabid et al. demonstrated stimulated Raman scattering in a hydrogen‐filled HC‐PCF , and other authors such as Fini also demonstrated the efficiency of HC‐PCFs in chemical sensing, with analyte–light overlaps over 90% . Their applicability for gas sensing or Raman spectroscopy was also demonstrated.…”

This paper provides an up-to-date overview on the use of microstructured optical fibers (MOFs) in chemical sensing during the last ten years, more specifically, applications in liquid media including the use of solid-core photonic crystal fibers, hollow-core PCFs and other MOFs and related microstructures. To this aim, a classification of different types of fiber-based chemical sensors is first made, followed by a description of the most important MOFs and their operation principles in chemical sensing. Then, studies on the use of MOFs in fluorescence, Raman and SERS detection among other detection principles are discussed. Finally, literature including the implementation of these microstructures in homemade and commercial analytical equipment is summarized. This review intends not only to give a current perspective on the use of MOFs and microstructures in chemical sensing, but also to make an approach between the fields of optical fiber and analytical chemistry, in order to understand the basic principles of operation in this promising frontier of knowledge.

“…This glass was chosen mostly for its thermo‐elastic properties that enable drawing of complex fiber structures at temperatures of only about 500° C. We do not expect any disadvantages in the optical performance of a silica fiber with identical geometrical structure, as the dispersion of this type of fiber is dominated by waveguide dispersion. The fiber structure combines ideas from several previously demonstrated guiding concepts . In particular, it has previously been recognized that the transmission and dispersion properties of the CPCF resemble those of a single ring‐like structure with dimensions close to the innermost layer of the fiber .…”

“…Consequently, photonic crystal fibers that are based on designs of equal cell size are essentially limited to beam delivery of pulsed radiation with temporal duration of 100 fs or above . For guiding of shorter pulses, it is necessary to use different guiding concepts, e.g., a Kagome structure or a chirped photonic crystal fiber (CPCF) , which has been demonstrated to be capable of guiding sub‐20 fs pulses over meter distance .…”

A novel fiber technology is presented that enables the transmission of 200 nm wide spectra over meter‐long distances with minimal temporal reshaping and acceptable losses down to about 3 dB/m. Delivery of a 10 fs pulse over nearly meter distance is experimentally demonstrated, which sets a new standard for the fiber‐based delivery of few‐cycle pulses. Numerical simulations provide insight into the unique guiding mechanism in the novel hollow‐core fiber technology, enabling dispersion parameters that are within an order of magnitude of those available in free space propagation.
