In optical communication networks, intensity fluctuation in optical signals is a critical issue through various processing such as transmission, amplification, switching. To solve this issue, we tried to improve performance of an optical limiter in dynamic range of fluctuation and compensation accuracy. In addition, we examined applicability to high repetition signal and nonlinear signal processing. As a result, we achieved a 40-Gb/ s and highly accurate intensity limiting with a single Erbium-Doped Fiber Amplifier(EDFA) for low-power-consumption driving intensity limiting.

在光通信网络中，光信号经过传输、放大、交换等各种处理后，其强度波动是一个关键问题。为了解决这个问题，我们试图提高性能的光限幅器的动态范围波动和补偿精度。此外，我们研究了高重复信号和非线性信号处理的适用性。结果，我们实现了40 Gb/ s和高精度的强度限制与一个单一的掺铒光纤放大器（EDFA）的低功耗驱动强度限制。
