Spectral Management of Entangled Two-Photon States

Abstract

We put forward a new approach for manipulating the spectral profile of entangled photon pairs. Such spectral properties are mediated by the geometry of non-collinear spontaneous parametric down conversion and by selecting spatial profiles of pump laser radiation.

We experimentally demonstrate an approach for manipulating the spectral profiles of entangled-photon pairs. The spectral properties are determined by selecting both the appropriate spatial profile of the pump laser radiation and the geometry of the noncollinear spontaneous parametric downconversion. Both spectra, the spectrum of the individual signal and idler photons, and the joint spectrum of the entangled-photon pairs, can be modified at will over a substantial range of values. This technique is therefore expected to be useful for an array of quantum-optics applications.

Quantum engineering for spatial control of entangled two-photon states

We put forward several techniques to engineer the spatial structure of entangled two-photon states in spontaneous parametric down-conversion, namely the direct manipulation of the pump beam, quasi-phase-matching engineering and the use of highly non-collinear configurations.

Spatial-to-spectral mapping in spontaneous parametric down-conversion

Silvia Carrasco, Juan P. Torres, Lluís Torner +3 more

We put forward an approach for manipulating the spectral profile of entangled photon pairs. Such spectral properties are mediated by the geometry of noncollinear spontaneous parametric down-conversion and by selecting the appropriate spatial profile of the pump laser radiation. We show that one can translate spatial features imprinted in the pump beam into desired spectral profiles of the generated entangled-photon state. Particular configurations suitable for generating entangled pairs with ultranarrow spectral width and with multiple-peaked spectra are demonstrated.

Two-Photon Spectral Amplitude of entangled states is engineered to produce a losslessly decomposition in non-overlapping single Schmidt modes. The method relies on spontaneous parametric down-conversion pumped by a comb-like spectrum radiation.
