摘要
We conduct an experimental study of cross-phase modulation efficiency for semiconductor optical amplifiers with two different active regions offset quantum-well (OQW) stack and centered quantum-well (CQW) stack. OQW devices exhibit less than 100 phase change, whereas CQW devices are 60% more efficient for the same pump input power, with more than 200 phase change possible. The input wavelength degrades the phase change significantly outside the 30-nm gain bandwidth window.
