We report visible supercontinuum generation initiated by the second harmonic generation obtained in a germanium-doped microstructured optical fiber after optical poling processing. The visible spectral broadening is due to a cross-phase modulation effect between the generated IR solitons and the second harmonic (532 nm) of the 1064 nm pump wave. The 400-650 nm white-light emission is obtained on the fundamental propagation mode of the fiber.
我们报道了在光学极化处理后的掺锗微结构光纤中，通过二次谐波产生引发的可见超连续谱产生。可见光谱展宽归因于所产生的红外孤子与1064 nm泵浦波的二次谐波（532 nm）之间的交叉相位调制效应。在光纤的基模上获得了400 - 650 nm的白光发射。
