Optical Micro–Nano Structures and Devices: Materials, Design and Applications

Dear Colleagues,

The terahertz band (0.1 THz–10 THz), scarcely exploited compared to other electromagnetic waves, has been receiving enourmous attention around the world. Photonic devices exploiting this frequecny band offer promise in a very diverse range of applications, such as biosensing, medical imaging, and 6G wireless communication technology, to name a few. This may be attributed to their large potential for molecular label-free fingerprinting,  as well as their non-ionizing properties and broad spectral bandwidth.

The realization of sensitive, high-speed and high-efficiency micro–nano devices for wireless communication, integrated circuits, and miniaturized interconnections requires materials and structure designs with strong light–matter interactions. However, approaches for generation, transmission, and conversion of terahertz electromagnetic waves are still limited. Therefore, novel materials and their micro–nano structures, exhibiting strong responses, extremely high electromagnetic confinement, and enhanced light–matter interactions, are in urgent demand.

This Special Issue aims to report on novel physical phenomena and machnisms in new emerging materials (metals, semiconductors, two-dimensional materials, topological materials, etc.) for emission, manipulation, and detection of terahertz electromagnetic waves, as well as the design and fabrication of micro–nano structures (cavity, metasurfaces, antenna, etc.) and devices for terahertz emission sources, modulators, and detector sand focal plane arrays for THz imaging.

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. Micromachines 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 2100 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.
