摘要:
Preform for an optical waveguide containing a core with a non-circular geometry and at least one cladding layer, in which the dopand concentration of the cladding layer is increased compared to the dopand concentration of a preform with circular core geometry and identical NA. A method for the production of a preform for an optical fiber is provided. An optical waveguide with a nominal dopand concentration of c(eff) x F≦c(nom) in at least one cladding layer is also provided.
摘要(中):
包含具有非圆形几何形状的芯和至少一个包覆层的光波导的预成型件,其中与具有圆形芯几何形状和相同NA的预制棒的掺杂浓度相比,包层的掺杂浓度增加。 提供了一种用于制造光纤预制棒的方法。 还提供了在至少一个包覆层中具有标称掺杂浓度为c(eff)×F≦̸ c(nom)的光波导。
