Coherent THz Sources in Integrated Circuits at Room Temperature

Dear Colleagues,

The search for coherent THz sources has been of crucial importance during the last decade due to their use in both technological and medical applications. Integrated-circuit solutions, operating at room temperature, render fabrication cheaper, more flexible, and scalable. Scalability and reproducibility are appealing features of integrated circuit technology as they allow for both emission and detection control via a technique called aperture synthesis.

In this context, two-dimensional materials, such as graphene, topological insulators, and metamaterials, are promising candidates for such integrated, compact, and scalable solutions as they can operate at room temperature. Topology, in particular, contributes additional features to THz radiation, namely helicity-dependent emission and orbital angular momentum (OAM), adding to the applications of quantum optics and plasmonics in the THz range.

This Special Issue aims to highlight research on coherent sources of THz based on integrated circuit technology. We are particularly interested in generation and detection solutions produced in a joint effort of the photonics, condensed matter, quantum optics, and nano-fabrication research communities.

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. 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.
