Special Issue Information

Dear Colleagues,

We are pleased to invite you to submit an article to a new Special Issue of Photonics called ‘Fiber Optics and Mainstream Areas of Photonics’. Currently, such areas as machine learning, singular optics, and nanophotonics associated with the miniaturization of fiber-optic components to reduce their size and increase efficiency using nanostructures and metasurfaces are rapidly developing. Additionally, investigations of multidimensional systems and their complex collective dynamics can be carried out, for example, based on the approaches of nonlinear fiber optics in multimode optical fibers. Transmission of energy and information over long distances using hollow core fibers, the ability to control single photons to create practical quantum communication systems, and the creation of new types of lasers based on new materials not previously used in fiber optics are just some of the areas of photonics that are already actively interpenetrating and interacting with fiber optics methods. This issue of Photonics aims to highlight these interesting and rapidly developing areas at the junction of the mainstream areas of photonics and fiber optics. In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following: methods of machine learning in fiber optics, singular optics in fiber optics and practical quantum communication systems, use of nanostructures in fiber optics, including metasurfaces, new approaches in nonlinear fiber optics and multidimensional systems, new types of fiber lasers, and new waveguide mechanisms. We look forward to receiving your contributions.

Manuscript Submission Information

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. Photonics 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 2400 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.

The paper presents the results of theoretical and experimental studies of all-glass leakage channel microstructured optical fibers (MOFs) with a large mode area and low bending losses. These MOFs contain two layers of fluorine-doped silica glass elements with a reduced refractive index, different diameters, and different distances between them. A numerical analysis of the properties of these MOFs was performed using the finite element method. The leakage losses for the fundamental and higher-order modes were calculated in the spectral range from 0.65 μm to 1.65 μm. Simulation results show that the proposed MOF design allows for single-mode guidance in the spectral range from 0.92 μm to 1.21 μm with a bending radius of down to 0.08 m. The measured losses of the fabricated MOF with a core diameter of 22.5 μm and a bending radius of 0.1 m were less than 0.1 dB/m in the spectral range from 0.9 μm to 1.5 μm. It is demonstrated that the segments of this MOF longer than 5 m are single-mode. Full article

The optical properties of solid-core micro-structured optical fibers (SC MOFs) have been studied for a long time. The process of the energy outflow of the core modes has always been associated with the process of constructive interference of the core modes fields under reflection from the photonic crystal cladding. In this paper, we want to offer a new look at the light localization in the core of SC MOFs related to the behavior of spin and orbital parts of the Poynting vector of these core modes and singularities arising in it. Such an approach can help in forming a better understanding of the process of the core modes energy leakage and also in the creation of SC MOFs with a simplified design and low losses. Full article
