TDK Demonstrates the World's First "Spin Photo Detector" Capable of 10X Data Transmission Speeds
TDK Corporation announces 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 - 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.
Transferring mass amounts of data at higher speeds and with lower power consumption is an inevitable need as AI evolves. To process data and make calculations, data is currently transferred between CPU/GPU chips as well as from and to memory by electrical signals. Therefore, there is an increasing need for optical communication and optical interconnects, which offer high speeds that do not decrease with interconnect distance. Photoelectronic conversion technology is also gaining global interest as a very compact fusion of both optical and electronic elements.
