摘要：
The power transmission technology to the equipment is remained behind in contrast to the progress of wireless communication. The existence of wiring and its connections greatly restrict the location of use, installation, maintenance, and configuration of the equipment. Solutions of wireless power transmission may lead to major changes in society, such as new services and new industries as well as convenience. Wireless power transmission such as electromagnetic induction is beginning to be put into practical use in smartphone, etc., however there are issues in extremely short transmission distance, large size, heavy, and so on. Optical wireless power transmission will be an important technology for expanding the field of wirelessly usable equipment due to features such as small size, short, mid and long distance transmission. On the other hand, there are some problems to be solved such as efficiency and safety. In this presentation, I would like to discuss the possibility and challenges of optical wireless power transmission using VCSEL as a high output and high efficiency light source.
