Analysis of the Emission Features in Graded-Index Polymer Optical Fiber Amplifiers

Organic dye-doped polymer optical fiber amplifiers (POFAs) are suitable for achieving high gains in short distances in the visible region. This paper presents a computational analysis of the optimum pump power and signal wavelength as a function of fiber length, numerical aperture, and radial distribution of dopant, for the case of a graded-index POFA doped with rhodamine B.
