Researchers at Caltech unveiled a device capable of steering one beam of light using another in just 74 femtoseconds. This breakthrough involved a team led by Harry Atwater at Caltech. The demonstration utilized optical meta-surfaces to amplify the optical Kerr effect on a thin silicon film. This method bypasses electronic limitations, achieving speeds far beyond traditional light modulators. This technology promises revolutions in computing, communications, and advanced sensing.
