ABSTRACT
The combined effects of upconversion and pump excited state absorption losses on the gain from co- and contradirectionally pumped erbium-doped fiber amplifiers have been studied experimentally and simulated numerically. Our results indicate that for all fiber lengths, contradirectional gain is higher than codirectional gain at low pump powers, and codirectional gain becomes higher than contradirectional gain at higher pump powers.
