Latest Papers Related to OWPT 2024 on the Topics of Devices, Components and Systems

Dear Colleagues,

Electrical power transmission is an essential function of equipment. Although wiring, batteries, and energy harvesting have been used, these methods have various problems. Society can advance with new equipment and services by addressing the power transmission issue. Power transmission methods using light beams are attracting attention as promising technologies. The first method involves power transmission in wireless, which, similar to wireless communication, has greatly progressed society. Optical wireless power transmission (OWPT) is extremely promising because of its potential for long-distance power transmission, lack of electromagnetic interference, small size, and lightweight. The second method involves power transmission using an optical fiber. Power over fiber (PoF) has the potential to provide new value to infrastructure by being lightweight and taking advantage of features not provided in existing wiring, such as surge resistance and integration with extremely high-capacity communications.

These optical power transmission technologies will be applied in the near future to a wide variety of applications, from minute IoT terminals to home appliances, industrial equipment, mobilities such as electric vehicles, robots, and drones, and power transmission infrastructure in various environments where conventional methods are difficult to apply. On the other hand, although the basic technical functions of these optical power transmission technologies already exist, practical and commercial systems are still very limited, and thus, the activation of related research strongly demands the development of many applications. By clarifying the superiority of this optical power transmission, identifying the problems to be solved, and collecting the state-of-the-art features of this field, such as materials, devices, subsystems, systems, and applications, as well as safety and standardization, we can anticipate the creation of numerous societal benefits in the foreseeable future.

For this reason, we have decided to publish a Special Issue that contains the latest results. Although this field is related to energy and photonics technologies, it is configured by a wide range of technologies, such as materials, devices, systems, and applications, as described above. This Special Issue will target papers related to individual devices such as light sources and light-receiving devices, functional integration, systems, and applications of optical power transmission.

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.
