Computational analysis of the amplification features of active plastic optical fibers

摘要

Polymer optical fibers doped with organic dyes can be used as efficient optical amplifiers and lasers in the visible region. We computationally study the spectral evolution with distance of the poises propagating along such fibers. The main goal is tornanalyze the lasing threshold and the slope efficiency as functions of the fraction of spontaneous emission that contributes to laser emission. The discussion focuses on rhodamine-6G doped fibers.
