Improving quantum-noise reduction with spatially multimode squeezed light
نویسنده
چکیده
We consider the squeezed vacuum state emitted by a degenerate optical parametric oscillator below threshold. We show, by using a confocal cavity and an appropriate matching lens, that the observed level of squeezing can become largely independent of the spatial intensity configuration of the local-oscillator field. © 1997 Optical Society of America [S0740-3224(97)01002-3] PACS number(s): 42.50.Dv, 42.65.Ky

Extraordinary optical transmission of multimode quantum correlations via localized surface plasmons.
We demonstrate the transduction of macroscopic quantum correlations by Ag localized surface plasmons (LSPs). Quantum noise reduction, or squeezed light, generated through four-wave mixing in Rb vapor, is coupled to a Ag nanohole array designed to exhibit LSP-mediated extraordinary-optical transmission spectrally coincident with the squeezed light source at 795 nm. This first demonstration of th...
متن کاملSurpassing the standard quantum limit for optical imaging using nonclassical multimode light.
Using continuous wave superposition of spatial modes, we demonstrate experimentally displacement measurement of a light beam below the standard quantum limit. Multimode squeezed light is obtained by mixing a vacuum squeezed beam and a coherent beam that are spatially orthogonal. Although the resultant beam is not squeezed, it is shown to have strong internal spatial correlations. We show that t...
متن کاملQuantum Squeezed Light Propagation in an Optical Parity-Time (PT)-Symmetric Structure
We investigate the medium effect of a parity-time (PT)-symmetric bilayer on the quantum optical properties of an incident squeezed light at zero temperature (T=0 K). To do so, we use the canonical quantization approach and describe the amplification and dissipation properties of the constituent layers of the bilayer structure by Lorentz model to analyze the quadrature squeezing of the outgoing ...
متن کاملSpatial multimode structure of atom-generated squeezed light
We investigated the spatial distribution of quantum fluctuations in a squeezed vacuum field, generated via polarization self-rotation (PSR) interaction of an ensemble of Rb atoms and a strong near-resonant linearly polarized laser field. We found that the noise suppression is greatly effected by the transverse profile of a spatial mask, placed in both the squeezed field and the local oscillator...

Squeezing of light’s quantum noise requires temporal rearranging of photons. This again corresponds to creation of quantum correlations between individual photons. Squeezed light is a non-classical manifestation of light with great potential in high-precision quantum measurements, for example in the detection of gravitational waves [1]. Equally promising applications have been proposed in quant...
