Abstract
We explore the cascaded χ(2) nonlinear process of second-harmonic generation (SHG) + spontaneous parametric down-conversion (SPDC) for telecom photon-pair generation. We experimentally verify our analytical prediction of discrete temperature-tunable signal/idler sidebands around a ~ 1550-nm pump.
