TDK announces the world's first "Spin Photo Detector" capable of 10X data transmission speeds
TDK Corporation has announced that it has developed the world's first "Spin Photo Detector," a photo-spintronic conversion element combining optical, electronic, and magnetic elements that can respond at an ultra-high speed of 20 picoseconds (20 × 10⁻¹² s) using light with a wavelength of 800 nm [1] – more than 10X faster than conventional semiconductor-based photo detectors.
This new device is expected to be a key driver for implementing photoelectric conversion technology that boosts data transmission and data processing speed, particularly in AI applications, while simultaneously reducing power consumption.
