Analytical investigation and numerical modelling of optimum EDFA-RFA hybrid optical amplifier for augmented gain and reduced differential spectral gain in ultra-dense WDM environment

Erbium-Doped Fiber Amplifier (EDFA) system is analysed by using coupled mode equations and subsequently through simulations. We aim reduction in differential spectral gain (∆G) while maintaining high gain (G). Analytical elucidation explores pivotal gain influencing parameters which include input si...
