We gave measuring principal and experimental setup . the 8 - order spectrum of srs in elliptical optical fiber and the 12 - order spectrum of srs in circular optical fiber are observed 對圓芯光纖觀測到12級srs ,對橢芯光纖觀測到8級srs 。
In the paper , transmission loss , polarizing and nonlinear characters ( chiefly about srs spectrum ) in highly single mode silicon elliptical optical fiber and circular optical fiber are experimentally and theoretically researched 本文對石英系單模橢芯和圓芯光纖的傳輸損耗特性、偏光特性、非線性特性(主要是srs譜)進行了系統(tǒng)的實驗研究和理論分析,給出了實驗裝置和測試原理。
