Machine-translated · View original
The lab develops optical computing devices and systems by combining light, nanotechnology, and information science.
AboutAbout the lab
Combining "light × nano × information" to develop optical computing.
The Information Photonics Lab researches optical computing devices and systems that combine optical and nanoscale technologies with information technology.
Building on the knowledge and experimental techniques to design and tune optical physical systems at very small scales, the lab works on developing innovative devices that function at the macroscopic scale.
Its experimental work is wide-ranging, from proposing and demonstrating the basic principles of optical devices and systems to designing, building, and evaluating their functions.
On the lab's website, it is introduced under the name "Tate Lab" ("Tatelabo").
Key terms
- Optical computing
- A general term for new information processing technologies that use light as the medium of information and fuse optical technology with information technology
- Quantum dot
- A semiconductor nanoparticle. It is also a fluorescent material that exhibits diverse optical functions depending on its material, size, arrangement, and other factors
- Photon breeding
- A new concept for designing and fabricating light-source devices in which a minute physical system is tuned to generate photons matching its characteristics
ResearchResearch themes
Optical computing is a general term for new information processing technologies created by fusing optical technology and information technology, with light as the medium of information. Under the concept of "light × nano × information," this lab uses its knowledge and experimental techniques for designing and tuning minute optical physical systems to develop optical computing devices and systems that function at the macroscopic scale.
*Illustrative imageOptical Machine Learning Built with Quantum Dots
The lab builds neural networks, a model for executing machine learning, by randomly dispersing quantum dots. It evaluates performance by measuring fluorescence output at the single-photon level, and also works on machine learning demonstrations.
*Illustrative imageOptical IDs for Safe and Secure Semiconductor Chips
The lab proposes using the optical response of an unclonable "micro optical ID" attached to a semiconductor IC chip as chip-specific identification information for individual authentication. With micro optical IDs mass-produced by inkjet printing, it has demonstrated high uniqueness and stable readout.
*Illustrative imageRealizing Photon Breeding Devices
Photon breeding is a new concept for light-source devices in which a minute physical system is tuned to generate photons with specifications matching its characteristics. In SiC doped with Al ions, the lab demonstrated for the first time that a large modulation effect appears only for optical input that matches the annealing conditions.
