Abstract

The balanced photodetector (BPD) is an important component for high-speed coherent receiver. An optimization strategy of waveguide-based multi-quantum well (MQW) BPDs, operating at 1550 nm is demonstrated on a generic InP platform. Design parameters of BPD are optimized towards achieving the highest bandwidth for a responsivity through an algorithm based on Particle Swarm Optimization (PSO). We do so by establishing an equivalent circuit model of BPD and analyzing its opto-electronic transfer function through numerical modelling. We address the major bottlenecks of high-speed BPDs: transit time of generated carriers and RC loading in our model. The algorithm is able to provide multiple combinations of design parameters with the same output characteristics. The design methodology to integrate laser with optimized BPD is presented to successfully implement a coherent receiver.

利用粒子群优化技术优化通用 InP 平台上相干接收器的平衡探测器

平衡光电探测器（BPD）是高速相干接收器的重要组件。基于波导的多量子阱（MQW）BPD 的优化策略在通用 InP 平台上得到了验证，其工作波长为 1550 nm。通过基于粒子群优化（PSO）的算法，对 BPD 的设计参数进行了优化，以实现响应率的最高带宽。为此，我们建立了 BPD 的等效电路模型，并通过数值建模分析其光电传递函数。我们在模型中解决了高速 BPD 的主要瓶颈问题：生成载流子的传输时间和 RC 负载。该算法能够提供具有相同输出特性的多种设计参数组合。介绍了集成激光器和优化 BPD 的设计方法，以成功实现相干接收器。

期刊介绍： The IEEE Journal of Quantum Electronics is dedicated to the publication of manuscripts reporting novel experimental or theoretical results in the broad field of the science and technology of quantum electronics. The Journal comprises original contributions, both regular papers and letters, describing significant advances in the understanding of quantum electronics phenomena or the demonstration of new devices, systems, or applications. Manuscripts reporting new developments in systems and applications must emphasize quantum electronics principles or devices. The scope of JQE encompasses the generation, propagation, detection, and application of coherent electromagnetic radiation having wavelengths below one millimeter (i.e., in the submillimeter, infrared, visible, ultraviolet, etc., regions). Whether the focus of a manuscript is a quantum-electronic device or phenomenon, the critical factor in the editorial review of a manuscript is the potential impact of the results presented on continuing research in the field or on advancing the technological base of quantum electronics.
