Abstract

Two-pump fiber optical parametric amplifiers (2-P FOPAs) are investigated to obtain a broadband and flat gain simultaneously with a low pump-to-signal noise transfer. The analysis is performed based on the six-wave model to find the optimum pump wavelength separation and also the fiber length to simultaneously maximize the gain and minimize the noise transfer from the pump to the signal. The results of this paper show the potential of 2-P FOPAs for application in fiber optical communication systems; for example, wavelength division multiplexing (WDM).
