Introduction to the OWPT Conference

The 1st Optical Wireless and Fiber Power Transmission Conference

The Optical Wireless and Fiber Power Transmission Conference (OWPT) is an international conference on optical wireless power transmission, optical fiber power transmission, and related technologies.

The 3rd Optical Wireless and Fiber Power Transmission Conference (OWPT2021) will be held on April 19 (Mon.) - 22 (Thu.), 2021 as an online conference hosted in Japan as one of the conferences of the OPTICS & PHOTONICS International Congress 2021 (OPIC2021).

The OWPT Conference is intended to provide a central forum for updating and reviewing scientific and technical information on optical wireless power transmission and optical fiber power transmission by covering a wide range of fields from fundamental researches to systems and applications.

This conference is sponsored by the Optical Wireless Power Transmission Committee, The Laser Society of Japan in cooperation with several academic societies and associations.
