Matsuura Lab
Machine-translated · View original
The lab researches optical fiber communication, including sending both data and power over a single optical fiber.
AboutAbout the lab
Sending both data and power over optical fiber.
Building on optical fiber communication technology, the Matsuura Lab researches technologies that will be useful for future optical fiber and wireless communication, with a focus on demonstration experiments.
The lab works on power over fiber, which sends communication signals and electric power together through an optical fiber, and on transmission using hollow-core fiber, whose core is made of air.
Another research theme is a drone that is powered and controlled through optical fiber.
Key terms
- Power over fiber
- A technology that sends light as energy through an optical fiber together with communication signals, in order to power devices at remote locations
- Hollow-core fiber
- An optical fiber whose core, the path the optical signal travels through, is made of air rather than glass
- Nonlinear effects
- Phenomena caused by polarization inside the glass, and one of the problems of conventional optical fibers

ResearchResearch themes
Building on optical fiber communication technology, the Matsuura Lab carries out research and development of technologies that will be useful for future optical fiber and wireless communication, with a focus on demonstration experiments. Its research themes are power over fiber, hollow-core fiber transmission, and a power-over-fiber drone.
*Illustrative imagePower-over-fiber technology
This research sends communication signals and the power to run a base station at the same time over the optical fiber line leading to a mobile communication wireless base station. Using the lab's original double-clad fiber with a dual-core structure, it has succeeded in delivering more than 40 W of electrical power.
*Illustrative imageHollow-core fiber transmission technology
Glass optical fibers have had problems such as nonlinear effects, a limit on input optical power, and propagation delay. Taking advantage of the ultra-low nonlinearity of hollow-core fiber, whose core is made of air, the lab has succeeded in high-quality transmission experiments with optical signals exceeding 1 W.
*Illustrative imagePower-over-fiber drone technology
A drone's flight time is limited by its battery capacity. As a way to go beyond this limit, the lab studies a drone that is powered through optical fiber, with control also carried out over optical fiber communication. It has succeeded in flight experiments and control of a small drone.
