Special Issue Information
Dear Colleagues,
Optical fiber sensing is a transformative technology, offering high sensitivity, compact size, immunity to electromagnetic interference, and the ability to perform distributed and remote measurements in harsh environments. Among its diverse branches, refractive index-based and interferometric sensing techniques have shown exceptional promise in enabling precise, real-time monitoring across a wide range of scientific and industrial domains.
This Special Issue, titled “Optical Fiber Sensors: Refractivity and Interferometric Applications” aims to highlight recent advances and fundamental developments in the design, modeling, and deployment of optical fiber sensors that rely on refractive index variations or interference-based mechanisms. Contributions may span innovations in sensor architectures, signal processing, novel materials, and emerging application areas where high-precision sensing is essential.
We welcome original research articles and reviews covering both theoretical and experimental work. Topics of interest include, but are not limited to, the following:
- Interferometric fiber-optic sensors (e.g., Mach–Zehnder, Fabry–Pérot, and Michelson).
- Refractive index sensing using fiber Bragg gratings, long-period gratings, or evanescent wave sensors.
- Fiber-optic biosensors and chemical sensors.
- Resonator- and cavity-based fiber sensing systems.
- Optical coherence and phase-sensitive measurement techniques.
- Applications in structural health monitoring, biomedicine, environmental sensing, and industrial diagnostics.
- Hybrid systems integrating interferometric sensing with other modalities.
- Advances in demodulation and signal interpretation for interferometric data.
Through this Special Issue, we aim to foster interdisciplinary collaboration and present the state-of-the-art in refractivity and interferometric applications of fiber sensors. We warmly invite researchers from academia, industry, and national laboratories to contribute to this collection and help advance the field of precision fiber-optic sensing.
We look forward to receiving your valuable 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.
