In this paper, we present a new method, based on the theory of mode analysis, to calculate the absorption efficiency of symmetric or offset double‐clad optical fibers. Both symmetric and offset conditions have been analyzed. In principle, our results are consistent with, but more accurate than, those of previous ray‐optics methods. © 2003 Wiley Periodicals, Inc.
