The lab is working on third-generation semiconductor lasers.

AboutAbout the lab
Creating cutting-edge research
The Information Device Lab (Kondow Lab) studies new semiconductor materials and devices.
The lab studies photonic crystals, which are nanoscale ultrafine structures, and new semiconductor materials such as GaInNAs, through both theory and experiment.
The entire lab is also committed to developing devices for realizing third-generation semiconductor lasers.
On the lab's website, it is introduced under the name "Kondow Lab."
Key terms
- Photonic crystal
- A nanoscale ultrafine structure. In this lab, it is used for the mirrors of the laser cavity.
- Active layer
- The layer where the intensity of laser light is amplified.
- GaInNAs
- One of the new semiconductor materials the lab works with. In Japanese, it is read as "Geinasu."
