Amplification of single channel and three Wavelength division multiplexing (WDM) channels with 16 and 64QAM modulated signals is demonstrated using an SOA with holding beam in the non-transparency wavelength to minimize phase distortion. We demonstrate an optical gain of 10 dB for single channel and for each channel in WDM operation. We also show that, the performance with holding beam can provide with minimal phase distortions a better bit-error rate value when compared to the linear regime of SOA operation for the same output power level.

使用 SOA 对 16 和 64QAM 信号进行低失真放大

使用 SOA 演示了具有 16 和 64QAM 调制信号的单通道和三个波分复用 (WDM) 通道的放大，该 SOA 将光束保持在非透明波长，以最大限度地减少相位失真。我们展示了单通道和 WDM 操作中每个通道的 10 dB 光增益。我们还表明，与相同输出功率水平的 SOA 操作的线性机制相比，保持光束的性能可以以最小的相位失真提供更好的误码率值。
