Putting optical fibers to work in communication and measurement

The Micro-Optics Lab conducts applied research on optical communication and optical measurement based on optical fibers.
Behind this is the explosive growth in data traffic driven by the spread of Internet-based services, which has made increasing the capacity and density of optical fiber communication networks and strengthening their security urgent issues.
Optical fiber communication networks are increasingly being applied to distributed sensing, which measures temperature, pressure, vibration, and more continuously over space.
On the lab's website, the lab is introduced under the name "Yoshida Lab."

ResearchResearch themes

Driven by growing data traffic, optical fiber communication networks urgently need greater capacity, higher density, and stronger security. As applied research in optical communication and optical measurement based on optical fibers, this lab works on multicore fiber transmission, optical fiber measurement, light sources for optical communication and measurement, and optical covert communication.

Multicore Fiber Transmission↗

The lab develops high-capacity, high-density optical communication technology using multicore fibers, and is also expanding into quantum communication. It aims to build a communication system in which one core of an ultra-low-loss two-core fiber performs high-precision phase synchronization while the other carries out quantum key distribution.
