Paper Abstract

The far-field distribution of single-mode fiber is studied; the Gaussian approximation for it is analyzed based on the characteristic of beam propagation factor and then its rationality is explained. Through researching the matching efficiency between the far-field and Gaussian field, a new definition of divergence half-angle is presented according to the maximal matching efficiency method; furthermore, a formula of the maximal matching efficiency divergence halfangle as function of normalized frequency is given.
