The lab develops new measurement and spectroscopy technologies using optical frequency combs.
AboutAbout the lab
Exploring new spectroscopy with optical frequency combs.
The Asahara Lab researches the development of new measurement and spectroscopy technologies that use optical frequency combs as a light source.
In collaboration with the Minoshima Lab and the Kato Lab (Department of Engineering Science), it holds experiments, lab meetings, and various events jointly as the Minoshima-Asahara-Kato group.
In addition to research on dual-comb spectroscopy, the lab works on spectroscopy techniques extended into the spatial dimension, targeting metamaterials and optical vortices.
The lab proposes and demonstrates new spectroscopy techniques that make full use of optical frequency combs.
Key terms
- Optical frequency comb
- A light source whose optical frequencies are lined up at equal intervals, like the teeth of a comb. It is used as a ruler for measurement and spectroscopy.
- Optical vortex
- Light whose wavefront is twisted into a spiral, so that it rotates around its direction of travel.
- Metamaterial
- A material whose fine structures are artificially designed to show properties not found in natural substances.
