In a recent breakthrough, a team of researchers from the University of Tokyo have discovered a new way to create optical logic gates using graphene nanoribbons. These optical logic gates are made from two-dimensional (2D) materials such as graphene, and can be used to control light instead of electricity. This opens up a range of potential applications, from ultra-fast computing to optical signal processing. The team’s research is a major step forward for the development of future-generation photonic devices.
