| Research Abstract |
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.
