Light–Matter Interactions

  • Spotlight Summary by Periklis Petropoulos

    • High-speed RF spectral analysis using a Rayleigh backscattering speckle spectrometer
    • A pulse propagating along a length of optical fibre generates an echo that contains its fingerprint. This fingerprint can be made sharper depending on the pulse width, whereas the fibre length determines how frequently...
