Special Issue Information
Dear Colleagues,
Employing optical orbital angular momentum (OAM) in laser communication networks can provide better candidates to realize multi-channel information transmission, which brings in advantages such as larger channel capacity and higher spectral efficiency. Laser communication has been a fantastic driver for exploring the fundamental interaction of optical OAM with the channel environment. The intended use of OAM for point-to-point optical links has illuminated a range of interesting new challenges, where novel interactions of optical OAM with the turbulent and scattering environment have highlighted the need for new technology to overcome the distorting effects. Inspired by these advances in laser communication with OAM is the use of these unique optical interactions of OAM with the channel environment that has instigated novel sensor technologies and could be a new frontier for optical OAM. The scope of this Special Issue is to provide an overview of recent advances in the developments and application of optical OAM in the channel environment. The scope encompasses fundamental research, interaction mechanisms, technology development, optical communication, and remote sensing applications of optical OAM. Both original research articles and comprehensive reviews are welcome.

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.
