Information Photonics Lab
Machine-translated · View original
The lab combines optics and information science to create new information technologies.
AboutAbout the lab
Creating new value for information technology through the physics and technology of light.
The Information Photonics Lab conducts research on creating information systems with new value, building on the physics and technology of light and combining it with information technology, mathematical science, and more.
From four directions, namely computing with light, observing with light, connecting with light, and contributing to medicine with light, the lab works on optical computing, optical imaging, and more.
Toward a human-centered super-smart society, the lab aims to develop technologies that connect the real world (physical space) and the virtual world (cyberspace).
Although the lab belongs to the Graduate School of Information Science and Technology, undergraduates from the Applied Physics Course of the School of Engineering's Department of Applied Science can also join as members.
Key terms
- Optical computing
- A technology that performs computation with light by combining the physical phenomena of light with computational models. It takes advantage of the parallelism and high bandwidth of light
- Optical Ising machine
- A computing device specialized for solving combinatorial optimization problems, implemented with light
- Computational imaging
- A technology that captures objects even in situations that are hard to image, by combining encoding through optical system design with mathematical methods
- In silico evaluation
- Evaluating treatment effects and safety on a computer, rather than through experiments or clinical studies

ResearchResearch themes
Building on the physics and technology of light, the lab draws on information technology, mathematical science, image engineering, DNA nanotechnology, and more to create information technologies and systems with new value. Specifically, it aims to develop high-performance optical computing systems, highly functional sensing and imaging technologies, and optical interfaces that connect people and objects with information.
*Illustrative imageComputing with light (optical computing)
The lab studies computation that takes advantage of the parallelism and high bandwidth of light. Its work includes optical reservoir computing for processing time-series signals, optical Ising machines specialized for combinatorial optimization problems, and optical DNA computing that uses the binding properties of DNA.
*Illustrative imageObserving with light (computational imaging)
This research aims to capture objects in situations that are difficult to image with just a lens and an image sensor, such as in fog or in dark environments. The lab works on object identification with a single-pixel detector and on multimodal imaging that simultaneously captures the amplitude, phase, and polarization of light, and it is also pioneering new imaging technologies that use cyber-physical systems.
*Illustrative imageConnecting with light (optical interfaces)
The lab studies technologies that use light to connect the physical space where people and objects exist with the cyberspace where information is handled. Its work includes the generation and application of vector optical fields based on computer-generated holography, physics-based security that uses nanoscale optical phenomena, and visual interfaces that support the activities of older adults.
*Illustrative imageContributing to medicine with light
The lab studies new optical diagnosis and optical therapy that make use of the properties of light. Using methods such as image processing, signal analysis, simulation, and AI, it is also building an in silico evaluation platform for assessing treatment effects and safety on a computer.
