为了互联网的可持续发展，波长可调谐光再生是在保持网络灵活性的同时扩大高能效动态光路网络的关键。基于高非线性光纤中参量放大增益饱和效应的波长可调谐光参量再生器（T-OPR）在相移键控信号的降噪方面具有广阔的应用前景。在本文中，我们实验评估的T-OPR性能的ASE退化43 Gb/s的RZ-DPSK信号在20 nm的输入波长范围内1527 nm和1547 nm之间。结果表明，在适当的泵浦功率范围内，再生闲频激光器的功率损失性能得到了改善。(C)2011年美国光学学会
For sustainable growth of the Internet, wavelength-tunable optical regeneration is the key to scaling up high energy-efficiency dynamic optical path networks while keeping the flexibility of the network. Wavelength-tunable optical parametric regenerator (T-OPR) based on the gain saturation effect of parametric amplification in a highly nonlinear fiber is promising for noise reduction in phase-shift keying signals. In this paper, we experimentally evaluated the T-OPR performance for ASE-degraded 43-Gb/s RZ-DPSK signals over a 20-nm input wavelength range between 1527 nm and 1547 nm. As a result, we achieved improved power penalty performance for the regenerated idler with a proper pump power range. (C) 2011 Optical Society of America
