Noise characteristic of dye-doped polymer optical fiber amplifiers

The noise in polymer optical amplifiers is mainly derived from the amplification of spontaneous emission (ASE). In this paper,the noise characteristic of dye-doped polymer optical fiber amplifiers is studied. The propagation equations of ASE power and the rate equations of dye molecular concentration are found based on the energy level transition of dye. The noise characteristic of optical fiber amplifiers is given by solving above equations numerically,and the relationship between noise figure and paramete...
