| 摘 要： | 针对光子晶体光纤之间直接熔接损耗较大的问题.文中采用纳秒激光器作为泵浦源,通过光子晶体光纤与单模光纤HI-1060低损耗熔接的方法,研究了超连续谱的展宽过程,分析了超连续谱的产生机理.实验结果表明：泵浦源在重复频率为150kHz、泵浦功率为2.2W时,利用20m的光子晶体光纤与1m的单模光纤的熔接实现了输出功率为0.48W、光谱范围超过1100nm的超连续谱输出.

| Abstract: | The experimental system of Supercontinuum generation by fiber splice has been demonstrated.In this system,photonic crystal fiber and normal single-mode fiber are used to reduce loss in order to solve the problem of splice among photonic crystal fiber.With a nanosecond pulsed laser as the pump source,the photonic crystal fiber and single-mode optical fiber of HI-1060 were spliced,on the basis of which the broadening process was analyzed.The results show that the 0.48 W supercontinuum with the spectral range over 1100 nm was demonstrated in splicing of a 20-m-long photonic crystal fiber and 1-m-long single-mode optical fiber at the average pump power of 2.2 W and the repetition rate of 150 kHz. |
