平均波长和输出功率稳定性高的掺铒光子晶体光纤超荧光光源的实验研究

采用掺铒光子晶体光纤代替传统掺铒光纤来提高超荧光光纤光源输出的功率稳定性和平均波长稳定性。在-45℃~70℃的全温区范围内，对超荧光光纤光源的光纤长度和半导体激光器(LD)抽运功率进行优化，并提出了用插值法进行LD抽运功率的优化方法，在光纤长度优化的基础上，高效、精确地优化了抽运功率，改善了光源的平均波长稳定性。经过优化的光源，在-45℃~70℃的全温区范围内平均波长变化量为0.67×10-6 /℃，输出功率稳定性为0.37%。

Abstract

Erbium-doped photonic crystal fibers (EDPCFs) are used to improve the output power and mean wavelength stability of the superfluorescent fiber source (SFS) instead of common erbium-doped fiber. Fiber length and pump power are both optimized at a large temperature range from -45 ℃ to 70 ℃ . An interpolatefitting method is used to optimize the pump power efficiently and precisely when the fiber length is optimized firstly. From -45℃ to 70℃ , the mean wavelength variation of the SFS is 0.67 × 10-6 /℃ , and the output power variation is 0.37%.
