The Er/sup 3+/-fiber gain coefficient derived from a dynamic gain tilt technique

We describe a new method to determine the Er/sup 3+/-fiber gain coefficient using a dynamic gain tilt technique. The method is based on attenuation measurement, gain measurements and crossover optimization of dynamic gain tilt. Results demonstrate that this method is very simple, highly accurate and especially useful for extended band erbium doped fiber amplifiers (EDFAs) design.
