Abstract

We show that an intense linearly polarized pulse propagating in a nonbirefringent fiber squeezes the perpendicularly polarized vacuum fluctuations through cross-phase modulation. Unlike the generation of squeezed vacuum through self-phase modulation, the mechanism discussed here does not require the use of a nonlinear Sagnac interferometer to separate the pump from the squeezed vacuum.
