TDK Introduces the World’s First ‘Spin Photo Detector’ with 10X Faster Data Transmission for Future AI Systems TDK Corporation has announced the development of the world’s first “Spin Photo Detector”—an innovative photo-spintronic conversion element that merges optical, electronic, and magnetic components. This novel device achieves ultra-high-speed responsiveness of 20 picoseconds (20 × 10⁻¹² s) using light at a wavelength of 800 nm, making it more than ten times faster than traditional semiconductor-based photo detectors. It is poised to become a pivotal technology for advancing photoelectric conversion systems that accelerate data transmission and processing—particularly in AI-driven applications—while simultaneously cutting power consumption.
