Suppression of SBS in a photonic crystal fiber with periodically-varied core diameter
Suppression SBS photonic crystal fiber periodically-varied core diameter
2011/5/20
We experimentally demonstrate 7dB improvement in Brillouin suppression in a photonic crystal fiber by periodically varying the size of the air-hole-structure by only 7% amplitude while keeping a low a...

2008/4/23
在理论上建立起将受激布里渊散射（SBS）与激光大气传输过程相结合的激光补偿传输的数学模型,并进行了数值模拟，提出并证明了利用SBS阈值效应可以将相位共轭光会聚到目标上一个小面积上，从而在目标上主动获得小面积信标光斑。利用SBS实现激光大气补偿传输（传输距离250m）的实验研究,证实了上述理论预期。
