Nano-Optics and Light-Matter Interactions

Dear Colleagues,

Nano-optics and specifically interactions between light and matter at the nanoscale are a subject of rapidly increasing scientific importance and technical relevance. Nanoscale light–matter interactions possess notable advantages in spectroscopy, quantum computing, communication, data storage, and lasers. In the last few decades, light–matter interactions have been actively investigated in quasiparticles called polaritons. Polaritons arise from the interactions between electromagnetic fields and dipolar oscillations in the matter, including electrons, phonons, and excitons. Polaritons, with their half-light–half-matter nature, can have vastly different polarization and dispersion and are confined to the scale of nanometers. Such photonic quasiparticles make it possible to reveal various kinds of light–matter interactions and to produce optical functionalities to manipulate the properties and energy of light at the nanoscale. The related research has given a significant boost to the development of nano-optics and nanophononics.

This Special Issue will present comprehensive research outlining progress in the coupling of photons to material resonances (plasmons, phonons, and excitons) and welcome contributions focusing on optics and photonics, optical materials, optical spectroscopy, quantum physics, condensed matter physics, and optical chemistry. We sincerely invite relevant researchers to contribute to the growing field of light–matter interactions at the nanoscale.

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Nanomaterials 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.
