Abstract

This paper presents an analytical comparison of three receiver architectures (PIN, APD, SOA-PIN) for 100 Gbit/s IM/DD fiber access links, under high optical budget constraints. Our results and the experimental results reported in the literature show that standalone PIN receivers cannot meet the required sensitivity for future PONs. GeSi APDs are promising thanks to their low avalanche noise and CMOS compatibility. However, the bandwidth of currently available GeSi APDs is still limited and needs to be further increased. SOA-PIN receivers, already mature and integrable, can achieve the target sensitivity but with limited power margin. Additional power margin can be achieved through proper design and engineering of the SOA-PIN. The effects of the noise figure, spontaneous emission factor and thermal noise are examined. The importance of low-noise SOAs and appropriate optical filtering is also discussed. Finally, trade-offs between sensitivity, bandwidth, integration and cost are addressed, along with design recommendations for next-generation access networks.

100gbit /s OOK IM/DD光纤接入链路接收机性能分析研究

在高光预算约束下，对100 Gbit/s IM/DD光纤接入链路的三种接收机结构（PIN、APD、SOA-PIN）进行了分析比较。我们的结果和文献中报道的实验结果表明，独立的PIN接收器不能满足未来pon所需的灵敏度。GeSi apd由于其低雪崩噪声和CMOS兼容性而前景广阔。然而，目前可用的GeSi apd的带宽仍然有限，需要进一步增加。SOA-PIN接收器已经成熟且可集成，可以实现目标灵敏度，但功率裕度有限。额外的功率余量可以通过SOA-PIN的适当设计和工程来实现。考察了噪声系数、自发辐射系数和热噪声对系统的影响。本文还讨论了低噪声soa和适当的光学滤波的重要性。最后，讨论了灵敏度、带宽、集成和成本之间的权衡，以及下一代接入网的设计建议。

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
