The lab designs tiny components that guide light, as well as semiconductor lasers.
AboutAbout the lab
Supporting society with new photonic integrated devices.
The Optoelectronics Lab studies devices that handle light, such as waveguides, which serve as pathways for light, and semiconductor lasers.
Through "new photonic integrated devices," the lab pursues research and development that is environmentally conscious and contributes to a society with a declining birthrate and an aging population.
Its research themes are the design of waveguides using nanostructures, semiconductor lasers that can be modulated at high speed, and compact sensors for analyzing breath and gases.
The lab's website is a joint website with the Optical Device Engineering Lab (Hamaguchi Lab), and it lists the members and research of both labs.
Key terms
- Waveguide
- A structure that guides light along a defined path
- Nanopixel structure
- A structure in which the waveguide region is divided into many small nanometer-scale sections (pixels)
- Photonic integrated circuit
- A circuit that combines small components that operate with light on a single substrate
