Special Issue Information
Dear Colleagues,
Underwater wireless communications refer to data transmission in unguided water environment through wireless carriers, i.e., radio-frequency (RF) wave, acoustic wave, and optical wave. In comparison to RF and acoustic counterparts, underwater optical wireless communication (UOWC) can provide a much higher transmission bandwidth and much higher data rate. In recent years, many potential applications of UOWC systems have been proposed for environmental monitoring, offshore exploration, disaster precaution, and military operations. However, UOWC systems also suffer from severe absorption and scattering introduced by underwater channels. Together with the absorption and scattering, underwater optical turbulence is also one of the most important physical events that prevent the optical waves to propagate long distances in underwater media. Various effects of underwater turbulence on the propagating optical wave, thus on the receive optical signal are studied. These effects substantially degrade the performance of UOWC links operating in underwater medium. In addition to single channel UOWC systems, multi-channel technologies, such as MIMO (Multiple Input Multiple Output) and OAM (Orbital Angular Momentum), are recommended to overcome turbuelnce-induced fading or enlarge the capacity with channel multiplexing. Such multi-channel modeling plays an importante role in the UOWC design.
This Special Issue aims at presenting an overview of UOWC channel modeling, recent progress, and furture trends. We welcome broad, visionary contributions of research reports as well as collection of reviews of accomplishments. We are excited to invite researchers to submit their contributions to this Spectial Issue.

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.
