Abstract

Amplification of high signal gain (36 dB, approximately 4000 times) and high output power (1200 W) was achieved in a Rhodamine B (RB)-doped graded-index (GI) polymer optical fiber amplifier (POFA) based on a prediction in which absorption and emission cross section data were used. The absorption and emission cross section spectra of RB, Rhodamine 6G, and 4-Dicyanmethylene-2-methyl-6-(p-dimethylaminostyryl)-4H-pyran (DCM) in poly(methyl methacrylate) (PMMA) bulk were determined. The cross section data enable us to predict gain characteristics of RB, R6G, and DCM-cloped GI POFA. The wide spectral coverage in the visible is achievable with the GI POFAs doped with several selected dyes.
