Special Issue Information
Dear Colleagues,
Photonic crystal fibers (PCFs), which also are usually known in the scientific literature as microstructured or holey fibers, were first proposed and experimentally confirmed by researchers from the United Kingdom in 1991 as alternatives to conventional optical fibers. To confine light in the solid or hollow cores of PCFs, well-ordered air channels are fabricated in their cladding around the cores along entire PCF lengths. Usually, the PCFs are fabricated from a single material, either glass or a polymer (plastic). The developed PCFs, for example, allowed for new possibilities in optical communication and sensing technology. This year at OFC 2024 (Th4A.8) it was revealed that a special PCF with optical losses of <0.11 dB/km for ultrafast next-generation optical networks had been created. Sensing devices based on PCFs have very small dimensions and weights similar to that of sensing probes, as well as a high immunity to electromagnetic fields. Further, it is not difficult to connect sensing probes with control systems. The PCF air channels can be filled with liquid analytic samples, endowing additional possibilities for sensing. Sensing devices based on PCFs have already been developed for measurement, displaying a very high sensitivity to curvature or bending, strain, pressure, temperature, refractive index, gas chemicals, biological quantities, and so on. The aim of this Special Issue is to review these achievements and to showcase new insights in the design, fabrication, and application of PCFs, as well as to inform readers about new developments in this field.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Crystals is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2100 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
