基于飞秒激光脉冲产生的宽带光谱和马赫-曾德尔干涉仪的实验装置,利用频域干涉法测量了光子晶体光纤(PCF)在800和1040 nm波长附近的色散特性,并与有限元法(FEM)计算结果相参照,证明了该频域干涉测量装置具有良好的测量精度和实用性。
The chromatic dispersion characteristics of PCF at 800 and 1040 nm were measured by frequency-domain interferometry based on the broadband spectra and the Mach-Zehnder interferometer produced by femtosecond laser pulses. The results were compared with the finite element method FEM). The results show that the interferometer has good accuracy and practicability.
