Study on Signal Intensity Stabilization for Ultra-fast Optical Signal Processing

在光通信网络中，光信号经过传输、放大、交换等各种处理后的强度波动是一个关键问题。为了解决这一问题，我们尝试从动态波动范围和补偿精度两方面提高光限幅器的性能。此外，我们还测试了该方法在高重复信号和非线性信号处理中的适用性。因此，我们通过单个掺铒光纤放大器（EDFA）实现了40 gb / s的高精度强度限制，实现了低功耗驱动强度限制。

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.
