Abstract :
We demonstrate, for the first time to our knowledge, a dynamic EDFA based on automatic active gain flattening. Wide-dynamic-range gain/power control is achieved with <0.6 dB signal ripple over 30 nm in various operating conditions. We also show a significant advantage of the dynamic EDFA over conventional one in cascaded structures.
