Abstract
We demonstrate the first fully on-chip electrically-pumped laser-integrated quantum photonic source, which consists of a laser cavity, an InP gain section, and a Vernier filtering stage. This sub-millimeter-sized hybrid chip generates high-quality, low-noise (CAR ~80) entangled photon states with a remarkably high pair detection rate (~620 Hz) over four resonant modes within the C-band. We confirmed the realization of high-dimensional entangled states with fidelity of ~ 0.99 and visibility of ~ 96%. This fully integrated, practical, and field-deployable quantum light source brings scalability to applications ranging from quantum processing circuits, quantum internet to quantum satellite systems.
