Dear Colleagues,

In recent years, we have witnessed a staggering growth of mobile data traffic due to the widespread use of wirelessly connected mobile devices. Due to the nearly exhausted radio frequency (RF) spectrum resource, it becomes challenging to support the ever-increasing mobile data traffic using conventional RF technology. As an emerging technology, optical wireless communications (OWC) have attracted tremendous attention lately, due to its inherent advantages such as license-free spectrum, large capacity, high security, no electromagnetic interference, etc. OWC can be implemented by using various wavelength regions including infrared (IR), visible light (VL) and ultraviolet (UV), and can be applied in various scenarios including indoor, outdoor and underwater environments. Nevertheless, the massive deployment of OWC systems faces several key challenges such as high transmission rate, low energy consumption, low latency, smooth handover, blocking and mobility, and flexible/robust system design.

The present Special Issue aims to attract contributions in all areas of OWC and publish high-quality research articles as well as review articles that seek to address the challenges of OWC systems, and in particular, that provide distinctive applications for future deployments.

Potential topics include, but are not limited to, the following:

• Novel electrical or photonic devices and components;
• Advanced modulation, coding, equalization and detection;
• Multiple-input multiple-output transmission;
• Multiple access and multi-user scheduling;
• Multi-cell/cellular network design and interference mitigation;
• Channel modelling and characterization;
• Transceiver nonlinearity compensation;
• Resource allocation and management;
• Hybrid and duplex system design;
• Privacy and security enhancement;
• Energy-efficient and cost-effective OWC;
• Artificial intelligence/machine learning-enhanced OWC;
• Visible light communication (VLC) using illumination LEDs;
• Co-design of communication and illumination control in VLC;
• LiFi architecture;
• VLC-based positioning and navigation;
• VLC-based ranging, detecting and sensing;
• Underwater optical wireless communications (OWC);
• Vehicular OWC;
• Optical camera communications (OCC);
• Application of OWC for data center.

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. Electronics 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.
