Emerging Terahertz Devices and Applications

Dear Colleagues,

This Special Issue invites the submission of innovative research that covers recent advances in emerging terahertz devices and applications.

Terahertz (THz) technology operates in the electromagnetic spectrum between microwaves and infrared, typically in the frequency range between 0.1 and 10 THz (wavelengths from 3 mm to 30 µm). This region, often called the "THz gap," has unique properties that can facilitate novel applications in imaging, sensing, communications, and biomedical diagnostics. This Special Issue aims to highlight recent advances in terahertz devices and their multiple applications.

We will consider academic and review papers that cover, but are not limited to, the following topics:

1. THz sources
2. THz detectors
3. THz modulators and components
4. THz applications such as:
   • Security and non-destructive testing;
   • Biomedical imaging and diagnostics;
   • Wireless communications (6G and beyond);
   • Astronomy and space science;
   • Material science.

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.
