摘要

基于超长半导体光放大器(UL-SOA)增益饱和的数据擦除/重写器是一种能够以高比特率和高消光比擦除调幅信号的新技术。然而，这种技术的主要缺点是在擦除之后发生的光谱展宽，这是由UL-SOA自相位调制造成的。因此，本文对该光谱展宽进行了实验分析。分析了一些参数的影响。测量到的主要谱宽为1.8 nm，这是波分复用应用中的一个问题。此外，本文还讨论了光谱展宽的不利之处以及如何减小这种不利之处。

Experimental analysis of the spectral broadening in a data eraser/rewriter based on a saturated UL-SOA

A Data eraser/rewriter based on the ultra-long semiconductor optical amplifier (UL-SOA) gain saturation is a new technique able to erase amplitude modulation signal at high bit rates with high extinction ratio. However the main drawback of this technique is the spectral broadening which occurs after the erasure, being the UL-SOA self-phase modulation the effect responsible for this. Therefore, experimental analysis of this spectral broadening is presented. The influence of some parameters is analyzed. The major spectral broadening measured was 1.8 nm, being a problem in WDM applications. Moreover, it is presented a discussion about how the spectral broadening can be prejudicial as well as how to reduce this drawback.
