## Abstract Injection locking of an erbiumβdoped fiber laserβamplifier is presented. Inside the locking range, the system oscillates at the wavelength of the injected signal. Outside the locking range, both signal and laser oscillate simultaneously in the cavity. Signal detuning studies show that t
For realizing wavelength-division multiplexing WDM transmission systems, one of the most important devices is the er-( ) bium-doped fiber amplifier EDFA , which exhibits a flat gain, a ( ) high pumping efficiency, and a low noise figure NF . To meet these requirements, we have optimized the hybrid E
Starting from the modeling of isolated ions and ion-clusters, a closed form rate and power evolution equations for high-concentration erbium-doped fiber amplifiers are constructed. Based on the equations, the effects of the fraction of ion-clusters in total ions and the number of ions per cluster on
