    "abstract": "We present experimental data of the frequency resolved optical gating (FROG)\nmeasurements of light pulses revealing interference features corresponding to\nsub-Planck structures in phase space. For superpositions of pulses a small,\nsub-Fourier shift in the carrier frequency leads to a state orthogonal to the\ninitial one, although in the representation of standard time-frequency\ndistributions these states seem to have a nonvanishing overlap.",
