Tsuda Laboratory - Connecting the World with Light: Building Photonic Networks

The internet, now an indispensable part of our daily lives, has been made possible by the development of "optical communication technology," which can dramatically reduce communication costs per amount of information and transmission distance. As an infrastructure supporting the next-generation internet and the coming ubiquitous environment, further advancements in optical communication technology are demanded more than ever. At the Tsuda Laboratory, under the slogan "Opticalization of Communications," we are advancing research in areas such as optical functional circuits, photonic networks, and ultra-high-speed optical signal processing, aiming for the further development of network infrastructure.

The Tsuda Laboratory is focusing on various optical functional circuits that utilize "optical waveguides." An optical waveguide is a structure that creates a path for light on a substrate, allowing the light to be confined, bent within it, or split in two. Among these, "silica optical waveguides," which use silica glass, are attracting attention as devices that can split or combine optical signals of different wavelengths.
