Rubidium-Doped KTiOPO${}_4$ Waveguides as a Dual-Type Photon Pair Source

Patrick Hendra, Josué R. León-Torres, Valerio Flavio Gili +1

We investigate the dual generation of type-0 and type-II spontaneous parametric down conversions (SPDCs) within a single periodically poled rubidium-doped KTiOPO${}_4$ (PPRKTP) waveg…
