Photonic Crystals: Physics and Devices, 2nd Edition

Dear Colleagues,

Photonic crystals offer an elegant platform to manipulate light at the micro- and nano-scale since they possess photonic band gaps where light transmission is prohibited. Over the past three decades, a series of physical effects including spontaneous emission, negative refraction, bound states in the continuum, Goos–Hänchen shifts, photonic spin Hall effects, topology, chirality, and nonlinear optical process have been widely studied in photonic crystals. Empowered by these physical effects in photonic crystals, many high-performance devices including mirrors, absorbers, filters, lasers, waveguides, fibers, polarizers, photodetectors, antennas, light-emitting diodes, logic devices, and solar cells have been designed. As promising building blocks in nanophotonics, photonic crystals not only promote the fundamental study of physical effects, but also facilitate the development of high-performance devices. Similar to photonic crystals, other classes of periodic nanostructures, i.e., metamaterials, metasurfaces, and subwavelength gratings, also exhibit the unique ability to manipulate light.

This Special Issue aims to present original state-of-the-art articles on physics and devices in photonic crystals and other classes of periodic nanostructures, including theoretical, numerical, and experimental works. We welcome both original research and review articles.

Topics of interest include, but are not limited to, the following:

• Photonic band gaps in photonic crystals (including one/two/three-dimensional photonic crystals and photonic crystal slabs);
• Resonances in photonic crystals, metamaterials, metasurfaces, and subwavelength gratings;
• Bound states in the continuum in photonic crystals, metamaterials, metasurfaces, and subwavelength gratings;
• Topological properties in photonic crystals, metamaterials, metasurfaces, and subwavelength gratings;
• Strong coupling in photonic crystals, metamaterials, and metasurfaces;
• Goos–Hänchen shift and photonic spin Hall effect in photonic crystals;
• Polaritons in photonic crystals;
• Nonlinear and quantum effects in photonic crystals;
• Photonic crystals containing two-dimensional materials, superconducting materials, phase-change materials, or metamaterials;
• Novel optical phenomena in photonic crystals;
• Devices based on photonic crystals;
• Physics and devices in other classes of periodic nanostructures, such as metamaterials, metasurfaces, and subwavelength gratings.

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.
