摘　　要：采用光纤环激光器为光源，色散位移光纤为非线性介质，利用光纤的非线性效应产生超连续（ｓｕ－ｐｅｒｃｏｎｔｉｎｕｕｍ）光谱信号，光谱宽度超过４０ｎｍ，采用Ｆ－Ｐ腔和可调谐滤波器滤波后成功地得到了１２个不同波长的超短光脉冲，每个波长的光脉冲重复频率为２．５ＧＨｚ，相邻波长间距为３．５ｎｍ。Utilizing an optical ring laser as the optical source, and a dispersion shifted fiber as the nonlinear material, a supercontinuum optical spectrum over 40 nm width was successfully generated. The WDM signals with a wavelength separation of 3.2 nm from the 12 wavelength channels each transmitting 30￣40 ps pulses at a repetition rate of 2.5 GHz are generated.
