Optical Fiber Sensors Development Based on Novel Smart Materials and Advanced Processing Technologies

Dear Colleagues,

In the field of optical sensing and detection technology, optical fiber sensing technology has become a hotspot with the fastest growth. Optical fiber sensing technology has the characteristics of being inherently passive, having a simple operation process, low cost, capable of long-distance transmission, as well as being resistant to electromagnetic interference, chemical corrosion, high pressure, and radiation. Based on the above characteristics, optical fiber sensors have broad application prospects in intelligent industry control, environmental pollution monitoring, pipeline leakage locating, structural health diagnosing, vital signs monitoring, and other fields. The development of high-performance optical fiber sensors increasingly depends on novel materials and advanced processing technology. Among them, novel functional materials cover semiconductors, metals (oxide), carbon materials, organic materials, etc. They exist in the form of zero-dimensional (carbon dots, semiconductor quantum dots, and metal nanoparticles), one-dimensional (carbon nanowires, semiconductor nanowires, and metal nanowires), two-dimensional (graphene, molybdenum sulfide, black phosphorus), and three dimensional (carbon nanotubes, etc.) structures. Various micro/nanostructures have been introduced to the surface or interior of optical fibers to develop "Lab on Fiber" and realize micro-area sensing with ultra-small samples and high precision. Relevant structures can be finely processed and regulated by means of UV nano-lithography, nano-imprinting, (focused) ion beam processing, chemical vapor deposition, (femtosecond or CO₂) laser micromachining, mechanical fine-grinding, etc. This Special Issue will focus on the development of high-performance optical fiber sensors based on novel smart materials and advanced processing technology, providing a technical discussion platform for scholars in related research fields.

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. Sensors is an international peer-reviewed open access semimonthly 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 2600 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.
