Seán P. Ó Dúill, Liam P. Barry

摘要:

我们提出了高精度和易于实现,改进的集总半导体光放大器(SOA)模型的单程和反射半导体光放大器(RSOA)。该模型的主要特点是包括内部损耗,我们表明,需要几个细分,以达到0.12 dB的精度。对于RSOA的情况下,我们概括了最近发表的模型来解释内部损失,这对复制观察到的RSOA行为至关重要。改进的减少RSOA模型的结果显示出大的重叠时相比,一个完整的双向行波模型在40 dB的动态范围内的输入功率和20 dB的动态范围内的反射率值。该模型将是有用的通信系统中的信号的快速系统仿真,即无源光网络,采用RSOA,使用SOA的信号处理和实施数字反向传播撤销放大器引起的信号失真。

英文摘要:

We present highly accurate and easy to implement, improved lumped semiconductor optical amplifier (SOA) models for both single-pass and reflective semiconductor optical amplifiers (RSOA). The key feature of the model is the inclusion of the internal losses and we show that a few subdivisions are required to achieve an accuracy of 0.12 dB. For the case of RSOAs, we generalize a recently published model to account for the internal losses that are vital to replicate observed RSOA behavior. The results of the improved reduced RSOA model show large overlap when compared to a full bidirectional travelling wave model over a 40 dB dynamic range of input powers and a 20 dB dynamic range of reflectivity values. The models would be useful for the rapid system simulation of signals in communication systems, i.e. passive optical networks that employ RSOAs, signal processing using SOAs and for implementing digital back propagation to undo amplifier induced signal distortions.
