Single-mode source of bright squeezed vacuum
Bright squeezed vacuum (BSV) can be obtained at the output of a high-gain traveling-wave optical parametric amplifier with the vacuum at the input. Without any special efforts, it is multimode both spatially and temporally. This means it comes as not Fourier-limited pulses and not diffractionlimited beams. At the same time, what theory describes well and what is required for most applications i...

متن کاملPartial angular coherence and the angular Schmidt spectrum of entangled two-photon fields
We study partially coherent fields that have a coherent-mode representation in the orbital-angular-momentummode basis. For such fields, we introduce the concepts of the angular coherence function and the coherence angle. Such fields are naturally produced by the process of parametric down-conversion—a second-order nonlinear optical process in which a pump photon breaks up into two entangled pho...
متن کاملSqueezed Vacuum Interferometry
A high-sensitive interferometric scheme is presented. It is based on homodyne detection and squeezed vacuum phase properties. The resulting phase sensitivity scales as ' 1 4 n 1 with respect to input photons number. Accepted for publication in Modern Phyiscs Letters B E-mail Address: [email protected]
متن کاملCoherent control of spectral and spatial features of bright squeezed vacuum states of light
In our work we investigate both theoretically and experimentally the spectral and spatial features and correlations in macroscopic (bright) squeezed quantum states of light generated in high-gain parametric down-conversion and referred to as bright squeezed vacuum (BSV). To describe theoretically these states we develop a generalized fully analytical approach, based on the concept of independen...
