TDK has just demonstrated the world's first "Spin Photo Detector" capable of 10x data transmission speeds for the next-gen of AI.

• A photo-spintronic conversion element capable of responding at ultra-high speeds of 20 picoseconds using light with 800 nm wavelengths, 10X faster than conventional semiconductor-based photo detectors
• Concepted and developed by TDK, the magnetic device can detect both near-infrared and visible light
• Successfully demonstrated operation in collaboration with Nihon University in Japan, known for fundamental physics research
• It can be applied to photoelectronic conversion technology, which is expected to improve data processing speed and reduce power consumption, both critical for further AI evolution
