Characteristics of parametric downconversion from a Bragg-reflection waveguide
Year: 2014
Type: preprint
Abstract: We investigate the properties of co-propagating twin beams created by parametric downconversion in a ridge Bragg-reflection waveguide. Our source is bright and efficient although the tightly confined waveguide modes are not perfectly compatible with standard single-mode fibre optics. We observe the coalesce of the twin beams and investigate the effect of the multi-photon contributions on the observed photon bunching. Our source shows a great potential for producing indistinguishable photon pairs as well as multi-photon states.
