An international team of researchers (Israel, Spain, France, USA – Kansas State University) shone pulses of light along the edge of a 2D material, producing in the material the hybrid sound-light waves. Not only were they able to record these waves, but they also found the pulses could spontaneously speed up and slow down. Surprisingly, the waves even split into two separate pulses, moving at different speeds. They developed a new technique to image the motion of light without disturbing it. According to the researchers having access to the full spatiotemporal dynamics of 2D wave packets can be used to illuminate puzzles in topological polaritons and discover exotic nonlinear optical phenomena in 2D materials. The work initiates the research of light pulses inside a novel set of materials, broadens the capabilities of electron microscopes, and promotes the possibility of optical communication through atomically thin layers…read more.
