| 英文摘要 | An optical fiber bidirectional amplifier includes a pair of small diameter optical fibers (12a, 12b), arranged in a side- by-side configuration, the first fiber (12a) providing a pumping source and the second fiber (12b) doped with a material which will lase at the frequency of the signal to be amplified. The signal to be amplified propagates through the second fiber (12b) to stimulate emission of coherent light from the lasing material, resulting in amplification of the signal. The refractive index of the first and second fibers (12a, 12b) is substantially identical, but the coupling characteristic provided by the geometrical relationship between the pair of fibers (12a, 12b) yields a wavelength dependent coupling efficiency. Specifically, the coupling efficiency at the wave- lenght of the pumping source is relatively high, while the coupling efficiency at the wavelength of the signal to be amplified is relatively low. Thus, the pumping illumination is coupled from the first fiber (12a) to the second fiber (12b) to stimulate the doping material in the second fiber (12b), while the signal to be amplified remains relatively uncoupled, and is amplified by the coherent light emitted by the lasing material. |
