Summary form only given. A vital issue for practical implementation of optical XOR gates is the tolerance of the gate towards imperfect synchronism of the two signals participating in the XOR operation, as well as the tolerance towards variations of

Influence of RZ and NRZ signal format on the high-speed performance of gain-clamped semiconductor optical amplifiers

Autor: David Wolfson, A. Kloch, T. Fjelde

Publikováno v: Fjelde, T, Wolfson, D & Kloch, A 2000, Influence of RZ and NRZ signal format on the high-speed performance of gain-clamped semiconductor optical amplifiers . in Proceedings on Optical Fiber Communication Conference 2000 . vol. 3, Baltimore, Maryland, USA, pp. 87-88, 2000 Optical Fiber Communication Conference and Exhibition, Baltimore, Maryland, United States, 07/03/2000 . https://doi.org/10.1109/OFC.2000.868531

High-speed experiments show that the influence from the limited relaxation frequency of GC-SOAs that severely degrades the performance for NRZ signals is reduced by using RZ signals, thus resulting in a higher input power dynamic range.
