Special Issue Information
Dear Colleagues,
The next 6G mobile generation will make extensive use of photonic technologies, both in the traditional application domains of these technologies, such as optical transport networks and data center interconnects, and in the opening of new application domains, such as photonic generation and processing of radio signals. In the optical transport network, 6G will push the need for high capacity and ultra-low latency further, also introducing new requirements, such as the tight synchronization of radio units in distributed MIMO scenarios. With the increase in the geographical density of antennas and their reduction in weight and size, guaranteeing high energy efficiency becomes important. Co-packaged optics (CPO) transceivers can guarantee several terabits of capacity with an energy efficiency of a few joules/bit. Radio over fiber (RFO) and power over fiber (POF) can make radio terminals smaller and less power consuming. Especially when extending the radio spectrum to millimeter-wave or Terahertz, photonics can greatly help in the generation and processing of radio signals with low phase noise, as well as in the implementation of low-loss distribution circuits for radio frequency or timing reference signals or the distribution of antenna signals for optical beamforming. Finally, 6G is expected to use a wider variety of technologies compared to previous mobile generations. Examples are free space optics (FSO), including satellite communications, and photonics-based sensors such as Lidars.
In this Special Issue, we invite submissions exploring the development of photonic technology and systems enabling the next 6G mobile generation. Contributions can focus on systems and devices for radio frequency generation and distribution, optical beamforming, co-packaged optics, radio over fiber, power over fiber, lidars, free space optics, satellite optical communications, and high-speed low-latency fronthaul networks. Survey papers and reviews are also welcomed.

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.
