Abstract
Modern photon pair generation methods for single photon state formation based on usage of photonic-crystal fiber
Incoming article date: 29.06.2016In the article managed photon pairs generation methods in lightguides with actively formed dispersion for producing a single-photon light state are discussed. Generation principle is based on of spontaneous parametric scattering or spontaneous fourwave mixing. To get the factored state, i.e. spectral and spatial correlations between daughter photons are eliminated, the usage of photonic crystal fiber, that allow to form complex frequency dispersion profiles by changing the fiber structure, is analyzed.
