Special Issue Information

Dear Colleagues,

The quest for innovative and reconfigurable, optically-transparent devices has increased over the last few years. This growing research interest has been driven by the opportunity to combine photonic and microwave technologies along with the exceptional e.m. properties of two-dimensional materials, such as graphene, thus opening new research avenues in fields such as cloaking, camouflage, nonlinear photonics, electromagnetic antipollution systems, telecommunications systems (IoT and 5G), and THz devices. In this scenario, the aim of this Special Issue is to share the latest results, in the form of articles and reviews, in the framework of graphene-based devices that operate at both microwave and optical frequencies. The Special Issue topics include but are not limited to: photonic crystals, plasmonics, integrated optical trapping, nanophotonic and plasmonic devices for nonlinear optics, modulators, and optically transparent microwave devices, such as absorbers, smart antennas, filters, metasurfaces, and metamaterials, which integrate graphene layers, Original contributions and concise reviews on any topic related to their applications in the microwave and photonic domains are also welcomed.

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. Applied Sciences 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 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.

Graphene is a material with exceptional optical, electrical and physicochemical properties that can be combined with dielectric waveguides. To date, several optical devices based on graphene have been modeled and fabricated operating in the near-infrared range and showing excellent performance and broad application prospects. This paper covers the main aspects of the optical behaviour of graphene and its exploitation as electrodes in several device configurations. The work compares the reported optical devices focusing on the wavelength tuning, showing how it can vary from a few hundred up to a few thousand picometers in the wavelength range of interest. This work could help and lead the design of tunable optical devices with integrated graphene layers that operate in the NIR. Full article
