ABSTRACT:
Several examples of double-pass fiber amplifiers including a polarization maintaining (PM) gain-fiber are disclosed. In each example, input and twice-amplified output are separated by an all-fiber, polarization-maintaining polarization splitter combiner. One example includes a double-pass fiber amplifier which relies on a double pass through a 45 degree fiber based rotator to rotate the polarization of the light.
