| Abstract: | An analytical expression of stable gain in an erbium-doped fiber amplifier (EDFA) was obtained by investigating the rate equations and propagation equations which describe the EDFA.In this paper it is also analyzed in detail that ground state and excited state ion density respond to the variation of signal,by which the linearitv of transient gain was explained. |
