Machine-translated · View original
A lab that uses silicon photonics to study photonic integrated chips and LiDAR.
AboutAbout the lab
Research on photonic integration that merges electronics and photonics.
The Baba Lab studies photonic integrated chips, silicon photonics, 3D image sensors, and biosensing in the fields of optoelectronics and photonics.
The lab has studied silicon photonics, which merges electronic and optical technologies, since the early days of the field, and has produced many technologies that are now widely used.
It also works on sensors that use light, such as LiDAR for autonomous driving and biomedical sensors that support health management and treatment.
The lab is also developing research that models complex structures such as photonic crystals and uses AI to search for new structures.
Key terms
- Silicon photonics
- A technology that builds optical circuits on silicon semiconductors, merging electronic and optical technologies
- LiDAR
- A 3D sensor that uses light to capture the surrounding environment in three dimensions. It is attracting attention as an in-vehicle sensor for autonomous driving
- Photonic crystal
- An artificial structure whose refractive index varies periodically at a scale comparable to the wavelength of light. It can control how light propagates
ResearchResearch themes
The Baba Lab studies photonic integrated chips, silicon photonics, 3D image sensors, and biosensing. It works on new optical technologies along the trends of communication networks and computers, IoT and sensing, and AI and photonics.
*Illustrative imageOptical communication and silicon photonics
Optical networks are expected to move into data centers and eventually reach the inside of integrated chips. The lab has studied silicon photonics, which merges electronic and optical technologies and will play the leading role in this shift, since the early days of the field.
*Illustrative imageAutomotive LiDAR and medical sensors
In the IoT, where things are connected to each other, the lab works on LiDAR, which is attracting attention as an in-vehicle sensor for autonomous driving, and on biomedical sensor technologies that support health management and treatment.
*Illustrative imageAI-driven search for optical structures
The lab models complex structures such as photonic crystals and searches for new structures with high performance without running huge numbers of simulations.
