Towards on-chip photon-pair bell tests: Spatial pump filtering in a LiNbO3 adiabatic coupler

Nonlinear optical waveguides enable the integration of entangled photon sources and quantum logic gates on a quantum photonic chip. One of the major challenges in such systems is separating the generated entangled photons from the pump laser light. In this work, we experimentally characterize double...
