我们研究了 V 参数的有效性,以确定光子准晶体光纤的单模工作状态。我们的结果表明,V 参数只能被考虑用于平滑变化的纤维。另一方面,对于在纤芯周围显示出孤立的高折射率区域的光纤,只有模面积分析才能估计单模工作状态的阈值。最后,这些发现可以推广到任何类型的光纤。
We have investigated the validity of the V parameter to identify the single-mode operation regime for photonic quasi-crystal fibers. Our results show that the V parameter can be considered only for smoothly changing fibers. On the other hand, for fibers showing isolated high refractive regions around the core, only a mode area analysis can allow the estimation of the threshold for the single-mode operation regime. Finally, these findings can be generalized to any kind of optical fiber.
