Abstract :
An inter-core crosstalk measurement method in a multi-core erbium-doped fibre amplifier that uses a single-wavelength signal with multiple intensity tones is investigated. Its feasibility is confirmed and the output signal power dependence of the crosstalk values for the same signal gains between cores is successfully characterised.
