Hybrid integration methods for on-chip quantum photonics

Je‐Hyung Kim, Shahriar Aghaeimeibodi, Jacques Carolan +2 more

The goal of integrated quantum photonics is to combine components for the generation, manipulation, and detection of nonclassical light in a phase-stable and efficient platform. Solid-state quantum emitters have recently reached outstanding performance as single-photon sources. In parallel, photonic integrated circuits have been advanced to the point that thousands of components can be controlled on a chip with high efficiency and phase stability. Consequently, researchers are now beginning to combine these leading quantum emitters and photonic integrated circuit platforms to realize the best properties of each technology. In this paper, we review recent advances in integrated quantum photonics based on such hybrid systems. Although hybrid integration solves many limitations of individual platforms, it also introduces new challenges that arise from interfacing different materials. We review various issues in solid-state quantum emitters and photonic integrated circuits, the hybrid integration techniques that bridge these two systems, and methods for chip-based manipulation of photons and emitters. Finally, we discuss the remaining challenges and future prospects of on-chip quantum photonics with integrated quantum emitters.The goal of integrated quantum photonics is to combine components for the generation, manipulation, and detection of nonclassical light in a phase-stable and efficient platform.

Hybrid Integration of Solid-State Quantum Emitters with a Silicon Chip

Je‐Hyung Kim, Shahriar Aghaeimeibodi, Christopher J. K. Richardson +3 more

Efficient generation and control of quantum light on a chip is very important to achieve scalable quantum photonic systems. Solid-state quantum emitters can generate single photons with high efficiency, while silicon photonic circuits can manipulate them in an integrated device structure. Combining these two material platforms, therefore, enable us to utilize the advantages of both systems and make feasible integrated quantum photonic devices. We demonstrate hybrid integration of solid-state quantum dots to a silicon photonic device by using a pick-and-place technique and perform Hanbury-Brown and Twiss experiments on the silicon chip with integrated quantum emitters.Efficient generation and control of quantum light on a chip is very important to achieve scalable quantum photonic systems.
