摘要：

The intensity-dependent nonlinear coefficient n(2)/A(eff) of a short Er-doped, amplifying fiber is determined using a method thoroughly studied for measurements of passive fibers. Measurement uncertainty of 3.0% is achieved using modified continuous-wave self-phase modulation method. In addition to metrological aspects, we also discuss limitations and conditions imposed by the Er-doped fiber as compared with the measurement of a pure silica core fiber. The used measurement method is advantageous as compared with other techniques due to its reliability and ease of implementation.
