摘要:
分析了级联二阶非线性全光波长转换中产生有限的泵浦与信号光带宽的原因，提出与论证了在准相位匹配光栅波导中引入非周期性分布的π相移域来增加泵浦波长可变范围的方法.结果表明可使波长调谐曲线的宽度和平坦性得到很大提高，泵浦带宽增加约4倍.
Abstract:
The paper analyzes the reason of producing the limited pump bandwidth and signal bandwidth on alloptical wavelength conversion based on the cascaded secondorder nonlinear effect,and proves the function of increasing the variable pump wavelength range if the π relative phase shift nonperiodically is introduced in QPM grating waveguides.The results show a flat tuning curves over a wide bandwidth are achieved,and the pump bandwidth increased by over 400%.
