Abstract :
A model is proposed to establish the relationship between the light coupling efficiency and fiber length for two contacted large fiber cores. The model correctly described the dependency of the coupled light on fiber length that was verified in the experiment with a twin-core fiber. This model can be used in fiber laser and erbium-doped fiber amplifier designs that employ twin-core or multicore pumping.
