Special Issue Information
Dear Colleagues,
The optical and geometrical uniqueness of photonic crystal fibres (PCFs) offers a new alternative in sensing, especially in gas sensing applications. The air holes of claddings and the core of PCFs open up new opportunities for exploiting the interaction of light with gases via evanescent field effects. The different arrangements of the air holes give a high range of design flexibility to build different PCFs (i.e., hollow-core PCF, microstructure core PCF, suspended core PCF, solid core PCF, kagome PCF) that diverse the gas sensing application with optical fibres. In addition to using direct light gas overlap in the evanescent field, PCFs are being tested for different new gas sensing techniques, such as long period grating in PCF, graphene-coated tapered PCF interferometers, and pulsed photothermal interferometers. These continuous investigations are improving the performance of PCF gas sensors and establishing different application fields.
This Special Issue will focus on the latest developments of gas sensing with PCFs, covering recent technological improvements and emerging applications.
We hope that this issue will provide a useful reference and that it will encourage further research on novel technologies and sensing devices with PCFs. Topics covered include but are not limited to:
- Modeling and numerical simulation of PCF gas sensors;
- Fabrication technologies of PCF gas sensors;
- Design, fabrication, and characterization of PCFs for gas sensing;
- New concept or approach of gas sensing with PCFs;
- Review of PCF gas sensing techniques and developments;
- Improving the sensitivity and response time of PCF gas sensors;
- Hollow core PCF-based gas sensing;
- PCF grating for gas sensing;
- Coating in PCF for gas sensing;
- Gas flow simulation in PCF.

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.
Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
