四极玻璃光纤中的多光束干涉

Multiple beam interference in a quadrupolar glass fiber

Martina Hentschel, Matthias Vojta

摘要:

基于最近对椭圆形微腔周期滤波特性的观察,我们研究了激光照射四极玻璃光纤远场中多光束的可能干涉。从数值射线跟踪模拟的实验情况下,我们得到的干扰相关的长度差谱,并将其与从实验滤波器结果中提取的数据进行比较。我们的分析表明,不同的多边形腔模式被折射耦合输出的光纤的高曲率区域有助于观察到的远场干涉。

英文摘要:

Motivated by the recent observation of periodic filter characteristics of an oval-shaped micro-cavity, we study the possible interference of multiple beams in the far field of a laser-illuminated quadrupolar glass fiber. From numerical ray-tracing simulations of the experimental situation we obtain the interference-relevant length-difference spectrum and compare it with data extracted from the experimental filter results. Our analysis reveals that different polygonal cavity modes being refractively output-coupled in the high-curvature region of the fiber contribute to the observed far-field interference.
