Abstract

The entropic definitions of beam spot sizes for optical fiber including mode-field radius as well as divergence half-angle are introduced and then the entropy-based beam quality factor is presented. Furthermore, relationships between the beam spot sizes and V-parameter are established for the convenience of calculation.

Keywords
