| Abstract: | In this paper, the relation between the gain characteristics and cross-sectional area of Er doped optical waveguide amplifier is developed by solving numerically propagation equations and rate equations. A new method of overlap factor is introduced based on the mode distribution of pump and signal. The range of optimum cross-section area was obtained. Finally, the importance of the overlap factor for the gain of waveguide is emphasized. |
