Abstract
This paper presents a study of multi-core erbium doped couplers as an alternative to conventional erbium-doped fiber amplifiers. The couplers can reduce the power unbalance between WDM channels along an optical communication link. Different configurations of couplers are analyzed and the influence of the number of cores is studied.
