Limiting amplifiers in optical systems
NettetFor optical amplification at 1.55 μ m, the erbium-doped fiber amplifiers (EDFAs) have been employed successfully in many undersea and terrestrial systems. We describe the appropriate index designs and processing technologies for active fibers that are key to their system implementation. NettetA comprehensive suite of steady state and dynamic optical amplifier models is provided, including advanced doped fiber models (Er, Er multi-mode, Er-Yb, Yb, Yb multi-mode, Tm, Pr) for detailed physical fiber amplifier design; EDFA and EDFA black box (gain spectrum, noise figure measurements) for WDM network systems design; dynamic and average …
