Special Issue Information

Dear Colleagues,

We are pleased to invite you to submit an article to a new Special Issue of Photonics called “Advances in Fiber Optics”. Optical fibers have experienced much success and have been applied in our daily life, in different industries, and in academia. They have continued to be rapidly developed since Dr. Kao and his collaborators reported on the possibility of optical fibers in telecommunication in 1966. Currently, areas such as new mechanisms and fabrication techniques, nanophotonic effects, and edge-cutting applications of optical fibers are attracting a large amount of attention. Notably, we can recognize the trend in developing fiber-optic components with miniaturized sizes and complex performances by either engineering the geometric features of optical fibers or integrating functional elements (2D materials, metasurfaces, and responsive media) into optical fibers. Additionally, there is increasing interest in novel active optical fiber devices and the nanophotonic capabilities of fiber optics.

This Special Issue welcomes works within all linear and nonlinear aspects of fiber optics, from fundamental studies to emerging applications. Submissions related to functional fibers with integrated nanostructures and new mechanisms and approaches of micro-structured fibers are strongly encouraged. 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.

Breath is one of the most important physiological features of human life. In particular, it is significant to monitor the physical characteristics of breath, such as breath frequency and tidal volume. Breath sensors play an important role in the field of human health monitoring. However, an electronic breath sensor is not stable or even safe when the patient is in a Magnetic Resonance Imaging (MRI) system or during any oncology treatment that requires radiation and other high electric/magnetic fields. Fiber-optic-based sensors have attracted a considerable amount of attention from researchers since they are immune to electromagnetic interference. Here, we propose and demonstrate a fiber-optic-based relative-humidity (RH)-sensing strategy by depositing Ti3C2Tx nanosheets onto an etched single-mode fiber (ESMF). The humidity sensor function is realized by modulating the transmitted light in the ESMF using the excellent hydrophilic properties of Ti3C2Tx. Experiments show that the coated Ti3C2Tx nanosheets can effectively modulate the transmitted light in the ESMF in the relative humidity range of 30~80% RH. The sensor’s fast response time of 0.176 s and recovery time of 0.521 s allow it to be suitable for real-time human breath monitoring. The effective recognition of different breath rhythms, including fast, normal, deep, and strong breathing patterns, has been realized. This work demonstrates an all-optical Ti3C2Tx-based sensing platform that combines Ti3C2Tx with an optical fiber for humidity sensing for the first time, which has great promise for breath monitoring and presents novel options for gas-monitoring applications in the biomedical and chemical fields.
