Spatial structure of a squeezed vacuum.
TLDR
This work considers the simplest quantum model for a degenerate parametric oscillator below threshold and analyze the quantum properties of the signal near field and introduces the idea of probing the emitted field by a local oscillator field of arbitrary spatial configuration to explore the spatial structure of the squeezed vacuum state emitted by the system.Abstract:
We analyze the quantum properties of the signal near field emitted by a degenerate parametric oscillator below threshold, including diffraction and its effects on the threshold for signal generation. The field is probed by a local oscillator field of arbitrary spatial configuration. The results are expressed in terms of an appropriate spectrum which describes how the level of squeezing varies with the angle from the direction of propagation. The results hold for cavities both with plane and with spherical mirrors.read more

Chapter 5 Quantum imaging
TL;DR: In this paper, the authors discuss the spatial aspects of local squeezing and quantum images, with related aspects such as the interference of signal and idler waves, as well as the quantum spatial correlations in spontaneous parametric down-conversion (PDC), ghost imaging, image amplification by PDC, and the detection of small displacements with a precision beyond the standard limit (quantum laser pointer).
