The Measurement of Broad-band Fiber-grating Transmi-ssion Spectrum using Tunable Fiber-grating Ring Laser
摘要
本文在理论分析基础上,用一种新颖的波长扫描光源,并采用自相关、波长解调装置,实现了宽带光纤光栅透射谱的测量。实验结果与精密光谱仪测量比较,误差小于5%,并与理论分析较好地符合。
Abstract
Based on the theoretical analysis, the transmission spectrum of a broadband fiber Bragg grating (FBG) have been measured by applying a passive wavelength demodulation system , in which a fiber Bragg grating wavelength scanning laser source is used. The FWHM and the peak reflectivity of the FBG to be measured is 0.48~nm and 94%, respectivly. The experiment result is in good agreement with that measured by an optical spectrum analyzer, with experimental error less than 5%.
