| Abstract: | Using Gaussian approximation of mode field, the analytical solution of the rate equations that describe an Er-doped fiber amplifier (EDFA) is investigated, and a formula of signal gain isobtained for single-mode pump in the case of small signal power. With this formula, it's easy to find the relations between signal gum and the main parameters Of fiber. This analysiS can facilitated the design of EDFA. |
