Noise and gain of an erbium-doped fiber amplifier for delay-line optoelectronic oscillator

In this paper, we present both theoretical and experimental analysis of erbium-doped fiber amplifier for delay-line optoelectronic oscillator. Theoretical investigation of erbium-doped fiber amplifier is performed by means of numerical model based on two-level approximation of active medium. The erbium-doped fiber amplifier design optimized for delay-line optoelectronic oscillator is demonstrated. The experimental study of phase noise and gain of the erbium-doped fiber amplifier is provided.
