A lab that controls light with magnetic properties to build new photonic integrated circuits.
AboutAbout the lab
Toward unprecedented photonic integrated circuits
The Shoji Lab studies photonic integrated circuits, which combine optical circuits on a single chip.
Aiming for new functions and high performance not seen before, the lab works on research related to photonics and spintronics.
Using the magneto-optical effect, the lab builds devices such as optical isolators, optical switches, and circuits that perform AI computation with light.
Key terms
- Photonic integrated circuit
- A circuit in which light paths and optical components are built together on a single chip
- Magneto-optical effect
- A phenomenon in which the magnetic properties (magnetization) of a material change the properties of light passing through it
- Optical isolator
- A component that lets light pass in only one direction and blocks light returning in the opposite direction

ResearchResearch themes
Aiming to realize photonic integrated circuits with unprecedented new functions and high performance, the lab works on research related to photonics and spintronics. Using the magneto-optical effect and other principles, it studies optical isolators, optical switches, optical computing circuits for AI, and visible-light devices for smart glasses.
*Illustrative imagePhotonic integrated circuits
The lab builds optical isolators, which block light reflected back into a semiconductor laser, using waveguides with magnetic garnet bonded onto them. It is also developing a technique to directly bond crystals with different properties together without using adhesive.
*Illustrative imageHigh-functionality optical switches
The lab studies wavelength-selective switches for building optical networks on a chip, and magneto-optical switches that can hold their state without power. It also works on optical memory, which stores optical information magnetically.
*Illustrative imageOptical computing circuits for AI
This research uses nonvolatile optical devices based on the magneto-optical effect to perform convolutional neural network computation on photonic integrated circuits. The lab also aims to realize artificial neuron devices that operate with optical signals.
*Illustrative imageVisible-light devices based on optical waveguides
Using planar beam scanners built on optical waveguides and the magneto-optical effect, the lab aims to realize thin, lightweight smart glasses with easy-to-see displays.
