Nanophotonic Information Applications Lab
Machine-translated · View original
The lab creates new forms of information processing with light and nanotechnology.
AboutAbout the lab
Light × nano × information: opening up optical computing.
The Nanophotonic Information Applications Lab studies nanophotonic information devices and systems that use nanophotonic technology to achieve advanced, practical functions.
Optical computing is a general term for new information processing technologies that use light as the information medium and combine optical technology with information technology.
The lab works on information applications that use light with diverse physical quantities, such as wavelength, polarization, and phase, rather than light intensity alone.
On the lab's website, it is introduced under the name "Tate Lab (Tatelab)."
Key terms
- Optical computing
- A general term for new information processing technologies that use light as the information medium and combine optical technology with information technology
- Polarization
- A property of light that focuses on the direction in which the light wave oscillates
- Quantum dot
- A nano-sized semiconductor particle that shows a wide variety of optical properties depending on its material, size, and arrangement
ResearchResearch themes
Under the concept of "light × nano × information," the lab designs and tunes optical physical systems at tiny scales, from microns down to nanometers, and develops optical computing devices and systems that function at the macro scale. The themes the lab is focusing on especially as of fiscal year 2026 are introduced below.
*Illustrative imageOptical Machine Learning with Quantum Dots
The lab builds neural networks by scattering quantum dots randomly. When light is input, fluorescence is output nonlinearly, and the lab is working on demonstrating machine learning that uses this effect.
*Illustrative imageNanophotonic Metrology for Ensuring Semiconductor Security
The lab proposes attaching a non-clonable "micro-optical ID" to an IC chip and using its optical response as chip-specific identification information for authenticating individual chips. With micro-optical IDs made by printing, the lab has demonstrated high uniqueness and stable readout.
*Illustrative imageControl of Nanoscale Physical Systems and Photon Breeding
The lab studies "photon breeding," in which a tiny physical system is tuned to generate photons suited to its characteristics. The lab was the first to demonstrate that SiC doped with Al ions shows a large modulation effect only for light that matches the annealing conditions.
