Special Issue Information
Dear Colleagues,
The emerging field of high-frequency vibrations in bulk semiconductors and low-dimensional systems is rapidly growing in close connection to optomechanics, surface acoustic waves (SAWs), and phonons and their coupling to photons and charge carriers. The dynamic modulation of semiconductor structures by high-frequency mechanical waves can provide a powerful tool for the control of the material properties required for novel functionalities in nanophotonics, nanoelectronics, and quantum information processing.
Optomechanical cavities constitute the potential building blocks of GHz-frequency in-chip phononic circuits for room-temperature operation, which will possibly integrate OM-pumped phonon sources and detectors. In addition, all standard electronic components, such as waveguides, splitters, and memories, are expected to be realized using phonons as state variables. Current research is aimed at providing efficient generation of GHz to tens of GHz coherent phonons and engineering phonon propagation with low losses. The important concept of synchronization of two or more self-sustained OM cavities is also highly relevant, as phonon processing will enable on-chip synchronization and transfer of information. In this context, of special interest are also SAWs: such acoustic waves can be effectively generated at high frequencies on a semiconductor chip with standard integrated circuit technology.
We are inviting the submission of manuscripts to this Special Issue, “Optomechanical Systems and Phononic Applications”, for publication in Applied Sciences. This Special Issue aims to address - but is not limited to - the experimental and theoretical/computational issues related to the characterization of mechanical waves and their possible interplay with other physical quantities, such as electromagnetic waves and charges, in a multiphysics framework. In particular, we welcome research articles as well as review articles on the significant recent progress of both computational methods and innovative experimental approaches.

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.
