Quadrature and polarization squeezing in a dispersive optical bistability model

Critical exponents in dispersive optical bistability

Noncritical quadrature squeezing through spontaneous polarization symmetry breaking.

We discuss the possibility of generating noncritical quadrature squeezing by spontaneous polarization symmetry breaking. We first consider Type II frequency-degenerate optical parametric oscillators but discard them for a number of reasons. Then we propose a four-wave-mixing cavity, in which the polarization of the output mode is always linear but has an arbitrary orientation. We show that in s...

Quadrature squeezing with ultrashort pulses in nonlinear-optical waveguides.

Using ultrashort laser pulses, we have observed quadrature squeezing and parametric gain in quasi-phase-matched KTiOPO(4) waveguides. Using a local oscillator pulse that is 2.5 times shorter than the squeezed pulse, we observed noise reduction of 12 +/- 1% below the shot-noise level. Parametric amplification and deamplification of a coherent seed pulse have also been observed, with no indicatio...

Polarization squeezing by optical faraday rotation.

We show that it is possible to generate continuous-wave fields and pulses of polarization squeezed light by sending classical, linearly polarized laser light twice through an atomic sample which causes an optical Faraday rotation of the field polarization. We characterize the performance of the process and we show that an appreciable degree of squeezing can be obtained under realistic physical ...
