Gain calculations in erbium-doped fibers using field approximations

In this paper, we compare the use of various field approximations of modal fields for gain calculations in erbium‐doped fibers. Our results show that the use of an appropriately chosen rectangular approximation leads to simple analytical expressions for the gain characteristics, and still retains su...

Description
Summary:In this paper, we compare the use of various field approximations of modal fields for gain calculations in erbium‐doped fibers. Our results show that the use of an appropriately chosen rectangular approximation leads to simple analytical expressions for the gain characteristics, and still retains sufficient accuracy. © 2001 John Wiley & Sons, Inc.
