Abstract

We present generation of photon-subtracted squeezed states at 860 nm, from nearly pure, continuous-wave squeezed vacua generated with a periodically-poled KTiOPO4 crystal as a nonlinear medium of a subthreshold optical parametric oscillator. We observe various kinds of photon-subtracted squeezed states, including non-Gaussian states similar to the single-photon state and superposition states of coherent states, simply by changing the pump power. Nonclassicality of the generated states clearly shows up as its negative region around the origin of the phase-space distributions, i.e., the Wigner functions. We obtain the value, -0.083 at the origin of the Wigner function, which is largest ever observed without any correction for experimental imperfections.

  29. Note that the squeezing levels shown in this paper are for the quadrature observables defined by ˆX= ∫ ∞ -∞ dtΨ0(t) ˆX (t). They can be directly evaluated with the initial squeezed vacua right after the OPO, using following expression; 2(ˆX)2=1-2 γT/ζ0 z(z+3) (z+1)(z+2)2. Here, z =pP/Pth is normalized pump power where P is pump power and Pth is an oscillation threshold of the OPO.
