Query: Real-time full bandwidth measurement of spectral noise in supercontinuum
  generation   The ability to measure real-time fluctuations of ultrashort pulses
propagating in optical fiber has provided significant insights into fundamental
dynamical effects such as modulation instability and the formation of
frequency-shifting rogue wave solitons. We report here a detailed study of
real-time fluctuations across the full bandwidth of a fiber supercontinuum
which directly reveals the significant variation in measured noise statistics
across the spectrum, and which allows us to study correlations between widely
separated spectral components. For two different propagation distances
corresponding to the onset phase of spectral broadening and the fully-developed
supercontinuum, we measure real time noise across the supercontinuum bandwidth,
and we quantify the supercontinuum noise using statistical higher-order moments
and a frequency-dependent intensity correlation map. We identify correlated
spectral regions within the supercontinuum associated with simultaneous
sideband generation, as well as signatures of pump depletion and soliton-like
pump dynamics. Experimental results are in excellent agreement with
simulations.
