On the relationship between pump chirp and single-photon chirp in spontaneous parametric downconversion
X. Sánchez-Lozano, Alfred B U’Ren, Jose Luis Lucio · Journal of Optics · 2011
We study the chronocyclic character, i.e. the joint temporal and spectral properties, of the single-photon constituents of photon pairs generated by spontaneous parametric down conversion. In particular we study how single photon properties, including purity and single-photon chirp, depend on photon pair properties, including the type of signal-idler spectral and correlations and the level of pump chirp.
