摘要

Numerical analysis for calculating the gain and noise figure (NF) of 7-cores hexagonal structured Multicore Erbium-Doped Fiber Amplifier (MC-EDFA) is carried out. In addition to this, a mode analysis has been carried out for the same geometric structure of the Erbium-Doped Fiber (EDF). The effect of different core radius, signal wavelengths are analyzed and the results are laid down in the form of gain and NF of the MC-EDFA, propagating mode, normalized frequency, maximum and minimum modal intensity in order to analyze the modal field confinement in the MC-EDFA. Along with this, the inter-core crosstalk has also been investigated for 7-cores Erbium-Doped Fiber Amplifier (EDFA). Results other than gain and NF, calculated with respect to the operating wavelength range from 1525 nm to 1565 nm are compared with the calculated gain for each core radius of the MC-EDFA so as to obtain an optimum set of conditions for designing a superior MC-EDFA. Thus, it is ascertained that the performance of a 7-cores MC-EDFA can be significantly improved by designing it with reference to optimum value of core radius and signal wavelength.
