Terahertz (THz) Science in Photonics

Dear Colleagues,

Terahertz (THz) photonics stands at the frontier of cutting-edge research, bridging the gap between photonics and electronics to unlock transformative applications in communications, sensing, imaging, and spectroscopy. The THz frequency range offers unique capabilities for non-invasive security screening, biomedical diagnostics, ultra-fast wireless communication systems (6G and beyond), etc. Despite its immense potential, challenges in achieving efficient THz generation, detection, and functional devices persist.

We are pleased to invite you contribute to this Special Issue of Photonics, which aligns closely with the journal’s scope and focuses on novel optical phenomena, materials, devices, and systems across the electromagnetic spectrum, including terahertz frequencies. Our goal is to compile a collection of ​​high-quality articles​​ that explore emerging paradigms in THz photonics. The aims of this Special Issue are to advance the understanding of THz light–matter interactions, device engineering, and system integration and to highlight cutting-edge advancements in terahertz science and technology, focusing on photonics-driven innovations.

This Special Issue welcomes original research articles and reviews. Research areas may include (but are not limited to) the following:

1. Novel THz sources and detectors.
2. Metamaterials, plasmonics, and metasurfaces for THz functional devices.
3. THz spectroscopy and imaging systems.
4. THz materials and physics.
5. Other applications of THz technology. 

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 250 words) can be sent to the Editorial Office for assessment.

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.
