Abstract

We consider the effect of squeezed input on quantum images in the output of the degenerate optical parametric oscillator. We find that the images can be made more intense than those produced using vacuum input. Moreover, adjusting the phase of the input light allows variation of the transverse wave vector for minimum fluctuations without affecting the output wave vector of maximum intensity. The use of spatially inhomogeneous squeezed input provides greater tuning of the spatial and nonclassical features of the output. In particular, writing quantum images becomes easy when diffractive effects and angle tuning of the input beams are utilized. [S1050-2947(99)10508-0].
