单模圆光纤中受激拉曼散射光谱偏振特性的研究

Study of Polarized Characters of Stimulated Raman Scattering Spectrum in Single Mode Circlar Fiber

研究了单模圆石英光纤在不同偏振光泵浦条件下,受激拉曼散射(SRS)各级斯托克斯光的拉曼阈值和频移特性,同时测试了光纤输出端的泵浦光和斯托克斯光的偏振状态.分析了偏振光在单模圆光纤中传输时偏振状态的变化.

The Raman threshold, frequency-shift and the states of Stokes spectrum of stimulated Raman scattering under the condition of different polarized pump light in single mode circle core optical fiber were studied. The polarization of pump and Stokes spectrum at output terminal of fiber were measured. The change of the polarized light transmitted in single mode circle core optical fiber was analysed.
