Wavelength and Temperature Dependence of the Er +3 Concentration in the Erbium Doped Fiber Amplifier

O. Mahran

Abstract

A core graded-index and erbium-doped concentration are studied and optimized for an Erbium-doped Fiber Amplifier (EDFA) in a two-level model. Also the dependence of both core graded-index and erbium- doped concentration on temperature and wavelength of the signal guided are studied. There is evidence to show that the core grad ed-index ha s obv ious influence on the gain bandwidth of the EDFA and the erbium concentration has effect on t he bandwidth of the amplifier also both core graded-index and erbium-doped concentration are approximate linear dependence on wavelength and temperature.
