全光纤脉冲压缩器 脉宽压缩 自相位调制 光量化 all-fiber pulse compressor pulse compression self-phase-modulation optical quantization
摘要
通过数值求解广义非线性薛定谔方程，研究了由高非线性光纤分别与3M-FS-PM-7811光纤和SMF-28光 纤串联构成的全光纤脉冲宽度压缩器在压缩波长为1550nm的红外光脉冲宽度方面的性能。计算结果表明：采用3M-FS-PM-7811光纤的 脉冲宽度压缩器所需要的入射功率小，而采用SMF-28光纤的脉冲宽度压缩器输出的脉冲基座小；两种全光纤脉冲宽度压缩器均 能将脉冲宽度为2ps的高斯输入脉冲压缩到200fs 300fs。
Abstract
Two all-fiber pulse compressors are fabricated by connecting a highly linear optical fiber with a 3M-FS-PM-7811 optical fiber and a 3MF-28 optical fiber in series respectively. Their infrared pulse width at the compression wavelength of 1550nm are studied by solving the generalized nonlinear Schrodinger (GNLS) equation numerically. The calculation result shows that the pulse compressor using a 3M-FS-PM-7811 optical fiber needs a lower input power and the pulse compressor using a 3MF-28 optical fiber can output a high-quality compressed pulse with a lower pedistal. Both all-fiber pulse compressors can compress the Gaussian input pulse with a pulse width of 2ps into a pulse with a pulse width of 200fs 300fs.
