本文提出了单模阶跃弱导光纤色散的一个物理意义较直观的公式。给出了u、du/dv和d

u/dv

的近似公式
使色散和零色散光纤参数的计算大为简化。此外
还对残余色散以及溶凝和淬硬石英的计算结果进行了讨论。
An alternative dispersion formula for monomode step-index weakly guiding optical fibers with more distinct physical insight is presented. Approximate expressions for u
du/ dv and d2u/dv2 are given in the range 1.5≤v≤3
which greatly simplified the calculation of both dispersion and zero-dispersion fiber parameters. The residual dispersion .and the influence of the difference between fused and quenched silica on total dispersion are also discussed.
