Orthogonal spatial coding with stimulated parametric down-conversion

open access: yesOptics Express, 2023
Orthogonal optical coding is widely used in classical multi-user communication networks. Using the phase conjugation property of stimulated parametric down-conversion, we extend the current time-domain orthogonal optical coding scheme to the spatial domain to encode and decode image information.

Parametric down-conversion beyond the semiclassical approximation [PDF]

open access: yesPhysical Review Research, 2020
Using a perturbative approach, we investigate the parametric down-conversion process without the semiclassical approximation. A Wigner functional formalism, which incorporates both the spatiotemproal degrees of freedom and the particle-number degrees of ...

Spatial Entanglement in Optical Parametric Down-Conversion

open access: yes, 2007
This chapter and Chapter 5 constitute a direct continuation of Chapter 1, with a description of the developments in the continuous variable approach to quantum imaging, achieved in the framework of QUANTIM. Whereas Chapter 2 treats the traveling-wave configuration for PDC, the discussion of Chapter 5 focuses on the cavity configuration of optical ...

Zeno Effect in Parametric Down-Conversion [PDF]

open access: yesPhysical Review Letters, 1996
Two examples are presented where the photon emission on spontaneous parametric down-conversion is prevented when attempts are made to infer the moment of emission. This inhibition is analyzed in terms of the disturbance caused on the system by the modifications that must be introduced in order to make possible such inference.

Generation of Squeezed States by Parametric Down Conversion [PDF]

open access: yesPhysical Review Letters, 1986
Squeezed states of the electromagnetic field are generated by degenerate parametric down conversion in an optical cavity. Noise reductions greater than 50% relative to the vacuum noise level are observed in a balanced homodyne detector. A quantitative comparison with theory suggests that the observed squeezing results from a field that in the absence ...

Multiparameter entanglement in femtosecond parametric down-conversion [PDF]

open access: yesPhysical Review A, 2002
A theory of spontaneous parametric down-conversion, which gives rise to a quantum state that is entangled in multiple parameters, such as three-dimensional wavevector and polarization, allows us to understand the unusual characteristics of fourth-order quantum interference in many experiments, including ultrafast type-II parametric down-conversion, the

Towards Measuring Terahertz Photon Statistics by a Superconducting Bolometer

open access: yesSensors, 2021
Statistical distributions of the analog readings of an antenna-coupled THz superconducting bolometer were measured and analyzed under a special type of irradiation by low-energy fluxes of THz photons with Poisson photon statistics and controllable mean ...
