TLDR
The photon-number-bandwidth correlation of the emerging soliton produces squeezing in the photon number of the filtered soliton, and bandwidth oscillations caused by the interference of the soliton with the quantum-noise continuum give oscillations of the photon- number squeezing and prevent achievement of arbitrarily high values of squeezing through spectral filtering.Abstract:
We study the quantum fluctuations of an optical nonlinear Schrodinger soliton after spectral filtering. The photon-number–bandwidth correlation of the emerging soliton produces squeezing in the photon number of the filtered soliton. Bandwidth oscillations caused by the interference of the soliton with the quantum-noise continuum, however, give oscillations of the photon-number squeezing and, in addition, prevent achievement of arbitrarily high values of squeezing through spectral filtering.read more

Physics and applications of atmospheric nonlinear optics and filamentation
TL;DR: Filamentation is a non-linear propagation regime specific of ultrashort and ultraintense laser pulses in the atmosphere that Typical applications include remote sensing of atmospheric gases and aerosols, lightning control, laser-induced spectroscopy, coherent anti-stokes Raman scattering, and the generation of sub-THz radiation.

Perturbation theory of quantum solitons: continuum evolution and optimum squeezing by spectral filtering.
TL;DR: Perturbation theory, including a quantum description of the continuum, is used to derive a complete analytical expression for the second-order correlator of the amplitude quadrature, which is subsequently used to optimize the frequency response of the filter numerically in order to achieve the minimum photon-number noise.

Quantum theory of soliton squeezing: a linearized approach
Hermann A. Haus,Yinchiah Lai +1 more
TL;DR: In this paper, a linearized quantum theory of soliton squeezing and detection is presented, which reduces the quantum problem to a classical one, and an optimal homodyne detector is presented that suppresses the noise associated with the continuum and the uncertainties in position and momentum.

Observation of Optical Soliton Photon-Number Squeezing.
TL;DR: The photon-number squeezing of optical solitons is reported, and a quantum field-theoretic model shows that the outlying spectral components have large energy fluctuations, so that their removal causes squeezing.
