Special Issue Information
Dear Colleagues,
Photonic integrated circuits (PICs) fabricated with materials such as silicon, III-V semiconductors, silicon nitride, tantalum pentoxide, titanium dioxide, etc. are being investigated for spectroscopic sensing from visible to infrared wavelengths. These platforms are explored for applications ranging from Raman spectroscopy, fluorescence spectroscopy, and absorption spectroscopy to refractive index sensing via interferometric methods. The field has been progressing rapidly in recent years, and excellent performance compared to the traditional spectroscopic methods has been reported, along with the promise of very compact and low-cost solutions.
Recent developments in PIC technologies have also raised the prospect of complete PIC-based system implementations, where passive and active photonic components and peripheral electronic components are all integrated together, thereby reducing the size, complexity, and cost of the system, while enhancing the system’s performance.
This Special Issue aims to publish high-quality manuscripts reporting the latest original research or review articles in, but not limited to, the following areas:
- Principles relevant to PICs for spectroscopic sensing;
- Materials relevant to PICs for spectroscopic sensing;
- Integrated photonic devices enabling spectroscopic sensing;
- Integrated waveguide technologies for spectroscopic sensing;
- Emerging applications in context of PICs for spectroscopic sensing;
- Raman spectroscopy using PICs;
- Absorption spectroscopy using PICs;
- Dual-comb spectroscopy using PICs;
- Fluorescence spectroscopy using PICs;
- Non-linear spectroscopy using PICs;
- Refractive index sensing using spectroscopic readout methods and PICs;
- Evanescent spectroscopic sensors;
- VIS, NIR, and mid-IR spectroscopic sensors using PICs.

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.
