Quadrature squeezing with ultrashort pulses in nonlinear-optical waveguides.
نویسندگان
چکیده
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 indication of gain-induced diffraction.

Pulsed squeezed-light generation in x (2) nonlinear waveguides
We present a brief history of experimental studies of quadrature squeezing, a tutorial on the physical origin and theory of squeezing, and our experimental study of squeezing by means of x (2) (second-order) nonlinear waveguides. We recently obtained 28% squeezing in quasi-phase-matched LiTaO3 waveguides, using picosecond pulses. The amount of squeezing appears to be limited primarily by blue-l...
متن کاملDecomposing a pulsed optical parametric amplifier into independent squeezers
Abstract We discuss the concept of characteristic squeezing modes applied to a travelling-wave optical parametric amplifier pumped by an ultrashort pulse. The characteristic modes undergo decoupled single-mode squeezing transformations, and therefore they form a useful basis to describe the evolution of the entire multimode system. This provides an elegant and intuitive picture of quantum stati...
متن کاملPulsed quadrature-phase squeezing of solitary waves in x „2... parametric waveguides
It is shown that coherent quantum simultons ~simultaneous solitary waves at two different frequencies! can undergo quadrature-phase squeezing as they propagate through a dispersive x (2) waveguide. This requires a treatment of the coupled quantized fields including a quantized depleted pump field. A technique involving nonlinear stochastic parabolic partial differential equations using a nondia...

متن کاملOptical parametric generation of nearly transform-limited mid-infrared pulses in dispersion-engineered nonlinear waveguides.
Optical parametric generation in dispersion-engineered waveguides fabricated by proton exchange in periodically poled lithium niobate is numerically investigated as a means for producing widely tunable mid-infrared ultrashort pulses starting from low energy pump pulses at a 1.55 microm wavelength and with 100 fs duration, which are typical parameters of amplified Er-fiber oscillators. Numerical...
