Emerging Technologies for 6G Space Optical Communication Networks

Dear Colleagues,

The 6G space-based optical wireless network represents a cutting-edge frontier of wireless communication technology, poised to revolutionize connectivity and information exchange in unprecedented ways. Building upon the state-of-the-art 5G radio frequency (RF)-based space communication system, the 6G space-based optical wireless network leverages the power of space-based optical communication to offer ultra-high data rates, ultra-low latency, ultra-low latency, massive connectivity, and high energy efficiency.

Compared with traditional radio frequency (RF) systems, space optical communication networks utilize laser diodes (LDs) or light-emitting diodes (LEDs) to transmit information through optical fibers and free space. However, the successful deployment of 6G space optical communication systems faces numerous challenges, including atmospheric effects, turbulence, pointing and tracking accuracy, and the need for efficient modulation and coding techniques.

The scope of this Special Issue includes, but is not limited to, the following topics:

1. Optical transceivers for space networks;
2. Free-space optical communication;
3. Satellite-to-satellite and satellite-to-ground optical communication;
4. Coding theory and applications for space networks;
5. Quantum communication and quantum key distribution in space;
6. Integration of space optical communication with terrestrial networks;
7. Performance evaluation and optimization.

By fostering collaboration and knowledge exchange, this Special Issue seeks to accelerate the development and deployment of the 6G space-based wireless network, ultimately shaping the future of wireless communication and connectivity on a global scale.

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.
