“…Such structures dramatically improve the brightness of solid-state quantum emitters with enhanced light extraction [39,40], and also improve the collection efficiency and generation rate of single photons by far-field engineering [33,41], and Purcell enhancement [42,43]. Furthermore, researchers are continually developing techniques for controlling the emitters' position [44,45], frequency [46][47][48], and dephasing [28] [40], which have brought solid-state quantum emitters to the forefront of quantum light sources. Comprehensive reviews on solid-state emitters and important developments can be found in Ref.…”

“…Atomically thin 2D materials are also of great interest as arrayed single photon sources with their flexibility and tunability. For example, positioning quantum emitters with 2D materials can be achieved by transferring the material on nano-patterned substrates, which induce a local strain that can form strain-induced quantum emitters at deterministic positions [48,104,105].…”

The goal of integrated quantum photonics is to combine components for the generation, manipulation, and detection of non-classical 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 article, 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. PHOTONIC INTEGRATED CIRCUIETS FOR QUANTUM PHOTONICSPICs provide a compact, phase stable, and high-bandwidth platform to transmit, manipulate, and detect light on-chip. By leveraging advances in semiconductor manufacturing for classical communication, PICs have been demonstrated with over a thousand active components in a few square mm [50].

“…3(b)), with purities reaching as high as 95% and detection rates up to 10 kHz; however, a withstanding challenge was that emitters were still appearing in a large spectral range of 720-800 nm, and also, these emitters were limited to cryogenic temperatures. Other strain-engineering methods have been explored following these demonstrations, such as metallic nano-cubes 42 and nano-particles 43 , nano-indentation with AFM tips 44 , and electrically controlled microcantilevers 45 . While each of these approaches have advantages, such as dynamical control over the extent of strain 45 or concurrently achieving Purcell enhancement 42,43 , overall, the emitters' purities were not comparable to nano-pillar approaches 31,32 .…”

The search for an ideal single-photon source has generated significant interest in discovering novel emitters in materials as well as developing new manipulation techniques to gain better control over the emitters' properties. Quantum emitters in atomically thin two-dimensional (2D) materials have proven very attractive with high brightness, operation under ambient conditions, and the ability to be integrated with a wide range of electronic and photonic platforms. This perspective highlights some of the recent advances in quantum light generation from 2D materials, focusing on hexagonal boron nitride and transition metal dichalcogenides (TMDs). Efforts in engineering and deterministically creating arrays of quantum emitters in 2D materials, their electrical excitation, and their integration with photonic devices are discussed. Lastly, we address some of the challenges the field is facing and the near-term efforts to tackle them. We provide an outlook towards efficient and scalable quantum light generation from 2D materials towards controllable and addressable on-chip quantum sources.

Large-scale optical quantum technologies require on-chip integration of singlephoton emitters with photonic integrated circuits. A promising solid-state platform to address this challenge is based on two-dimensional (2D) semiconductors, in particular tungsten diselenide (WSe 2 ), which host single-photon emitters that can be strainlocalized by transferring onto a structured substrate. However, waveguide-coupled single-photon emission from strain-induced quantum emitters in WSe 2 remains elusive.Here, we use a silicon nitride waveguide to simultaneously strain-localize single-photon

Abstract: By integrating WSe2 monolayers with a nanopatterned Si micro-cantilever, we create the quantum emitters at deterministic sites and control their frequency with voltages. Also, reduction of the fine-structure splitting is observed by engineering the strain.
