| 摘 要： | 为了研究全光波长转换的实现方法,采用色散位移光纤中脉冲光和连续波间的交叉相位调制效应,使得连续波产生频移和展宽,然后利用光纤光栅滤波,得到了重复频率为57.97MHz、脉冲宽度为2ns的转换脉冲,这与抽运脉冲重复频率、脉冲宽度基本相同,而且连续波可调范围是1537nm~1560nm。结果表明,基于色散位移光纤中交叉相位调制效应的波长转换具有较宽的波长转换范围和较快的转换速度,是一种简单、高效和通用的波长转换技术。

| Abstract: | The cross-phase modulation(XPM) between pulse train and continuum wave in dispersion-shifted fiber(DSF) is utilized to implement all-optical wavelength conversion.The frequency shift and broadening of continuum wave induced by XPM in DSF was experimentally observed.Then wavelength conversion was achieved through filtering by a fiber grating.The converted pulse train with repetition rate of 57.97MHz,pulse-width of 2ns and the modulation period of continuum wave of 1537nm~1560nm,almost as the same of pump pul... |
