About Our Project

Project overview:

The ever-growing digital transformation (DX) calls for a new-generation data processing technology featuring orders of magnitude increased bandwidth while consuming minimal power. Optical technology is crucial for propagating high data rates with low power consumption, raising an urgent demand for microelectronics with bandwidth comparable to the transmission speed of light to achieve integrated optical interconnects. Our team uses its expertise in spintronics and photonics to create ultra-fast and ultra-low power photoelectric devices that can substitute energy-hungry intermediate electronics for data processing. We envision such a device to generate a great leap forward in optoelectronics and communication technology.
