用微型空心光纤产生暗心光束

Far Field Distributions from the LP_(01) Mode in Micro-sized Hollow Optical Fiber

该文导出了微型空心光纤LP0 1模激励的远场分布解析表达式 ,并进行了数值计算 ,给出了远场分布图 .研究结果显示空心光纤中LP0 1模激励的出射光束为暗心发散光束 ,同时还给出了远场近场暗心光束的暗斑尺寸 .

We derive an analytical expression of the far field distribution of LP 01 mode and calculate numerically.The reswt studied shows that the output beam of the LP 01 mode in the hollow fiber is a dark hollow divergent beam. The dark spot size (DSS) of the beam in the far-field is also given.
