O+E+S+C Ultra Broadband Hybrid Optical Fiber Amplifier

In this work, a hybrid optical amplifier for O+e+s+cband amplification using Praseodymium doped fiber amplifier (PDFA), Thulium doped fiber amplifier (TDFA) and Erbium doped fiber amplifier (EDFA) is presented by optimizing amplifier's physical and geometric parameters. A signal gain (G)> 17.11 dB and noise figure (NF)< 3.23 dB with a maximum gain of 48.09 dB at 1310 nm have been observed for the wavelength region of 1265 nm to 1550 nm. The impact of nonlinear ion-ion interaction mechanism (IM) effect on signal gain is also observed and minimized by optimizing amplifier's geometric and physical parameters.
