Abstract
We will use integrated optical resonators made with lithium niobate (LiNbO3) and silicon nitride (Si3N4) to prepare heralded single photon states. The non-linearity of the materials allows for the creation of correlated photon pairs due toto the process of Parametric Downward Conversion (PDC) or mixture of four waves (4WM). When the material is placed inside an optical cavity, the feedbac…
