Proposed is a multi-core fibre amplification method that can reduce crosstalk, in which the optical amplified signals in two adjacent cores propagate in opposite directions. By employing the proposed… (More)
Fused taper type fan-in/fan-out device with small MFD is developed for multicore EDF. Almost similar MFD and high accuracy core arrangement as multicore EDF are achieved by using high Δ single-core… (More)
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… (More)
