我们展示了具有两个紧密分布的零色散波长的高度非线性光子晶体光纤中的超连续谱生成。光纤的特殊色散对超连续谱有着深远的影响，超连续谱是通过自相位调制和相位匹配四波混频产生的，而不是像最初的光子晶体光纤那样通过孤子裂变产生的。超连续谱具有高谱密度，并且在很宽的输入脉冲参数范围内与输入脉冲极其无关。模拟表明超连续谱可以被压缩为超短脉冲。 (C) 2004 年美国光学学会。
We demonstrate supercontinuum generation in a highly nonlinear photonic crystal fiber with two closely lying zero dispersion wavelengths. The special dispersion of the fiber has a profound influence on the supercontinuum which is generated through self-phase modulation and phasematched four-wave mixing and not soliton fission as in the initial photonic crystal fibers. The supercontinuum has high spectral density and is extremely independent of the input pulse over a wide range of input pulse parameters. Simulations show that the supercontinuum can be compressed to ultrashort pulses. (C) 2004 Optical Society of America.
