ABSTRACT In this study, the effects of facet reflectivity on the data erasure ability of injection-locked Fabry Perot Laser Diode (FPLD), based on a remodulation method in wavelength division multiplexed passive optical network (WDM PON), were investigated. For this purpose, the feasible front facet reflectivity of FPLD was determined as between 0.2% and 7%, depending on the specified injected power interval. Firstly, the system carried out analysis without applying data at the user end to comprehensively demonstrate how much downstream data was completely erased in FPLD. Then, 2.5 Gb/s of non-return-to-zero (NRZ) data was applied and the results compared with the erased downstream signal without data. The results show that upstream transmission improved with an increase in facet reflectivity between 0.2% and 7%.

法布里-珀罗二极管激光器中的数据擦除：小平面反射率的影响

摘要 在这项研究中，基于波分复用无源光网络 (WDM PON) 中的再调制方法，研究了小平面反射率对注入锁定法布里珀罗激光二极管 (FPLD) 数据擦除能力的影响。为此，FPLD 的可行正面反射率确定为 0.2% 到 7%，具体取决于指定的注入功率间隔。首先，系统在用户端没有应用数据的情况下进行分析，以综合展示FPLD中完全擦除了多少下游数据。然后，应用 2.5 Gb/s 的不归零 (NRZ) 数据，并将结果与​​没有数据的已擦除下游信号进行比较。结果表明，随着小平面反射率增加 0.2% 到 7%，上行传输得到改善。
