论文摘要
嵌入在混合圆形bragg光栅中的半导体量子点是有效产生非经典光的有前途的平台。具有相似性能的多个设备的可扩展制造对于它们用作单个和纠缠光子的来源的实际用途非常需要，而在电信波长下运行的能力对于与现有光纤基础架构的集成至关重要。在这项工作中，我们结合了宽带混合圆形布拉格式的有希望的特性，以及在3英寸晶片上执行的膜转移过程。我们基于INAS/GAAS量子点在电信O-band中发出的基于INAS/GAAS量子点进行开发和研究单光子源，该量子点在电信O-band中发出，证明了与Purcell ofer> 5和Purcell因子> 5 and Purcell Inceers for 5 and Countod for-5 MH的率。根据O带内的10 nm范围范围覆盖10个设备的性能进行基准测试。
Semiconductor quantum dots embedded in hybrid circular Bragg gratings are a promising platform for the efficient generation of nonclassical light. The scalable fabrication of multiple devices with similar performance is highly desirable for their practical use as sources of single and entangled photons, while the ability to operate at telecom wavelength is essential for their integration with the existing fiber infrastructure. In this work we combine the promising properties of broadband hybrid circular Bragg gratings with a membrane-transfer process performed on 3" wafer scale. We develop and study single-photon sources based on InAs/GaAs quantum dots emitting in the telecom O-band, demonstrating bright single-photon emission with Purcell factor > 5 and count rates up to 10 MHz. Furthermore, we address the question of reproducibility by benchmarking the performance of 10 devices covering a wide spectral range of 50 nm within the O-band.
