Strongly Coupled Single-Quantum-Dot–Cavity System Integrated on a CMOS-Processed Silicon Photonic Chip

Abstract

Integration of strongly coupled quantum-dot--cavity systems into silicon photonics is important for large-scale quantum photonic integrated circuits, to implement photon-photon interactions in optical quantum information processing, but technical difficulties have thwarted progress here. This study uses a transfer-printing method, which is applicable regardless of the materials used, to solve the problem. This approach is expected to have real impact on the production of quantum photonic integrated circuits.
