Research paperExperimental CharacterizationEffects due to generation of negative frequencies during temporal diffractionE. Hendry, C. M. Hooper, W. P. Wardley, S. A. R. Horsley2025·10.48550/arxiv.2507.03491·arXiv:2507.03491AbstractTemporal diffraction from rapidly time-modulated materials can generate new frequency components not present in an incident wave. In this experiment, the authors study graphene as a fast modulator in the far-infrared (THz) spectral region and show that its transmission can be modulated significantly faster than the period of a narrow-band THz field. This produces a broad bandwidth of scattered frequencies, including negative-frequency components, and leads to oscillatory interference features in the transmitted spectrum.Read more
