Burst-mode EDFA based on a mid-position gain flattening filter with an overpumping configuration for variable traffic conditions in a WDM environment

Abstract

The WDM flatness easily collapses due to substantial changes in input power, an inherent problem in optical packet communication because of dynamic changes in traffic density. We propose a burst-mode EDFA with a novel configuration based on the concept of a mid-position gain flattening filter (GFF) with overpumping. This configuration can effectively suppress gain transience while maintaining WDM flatness.

“…The degradation of power penalty might be induced by the pattern effect of EDFA. With the pattern effect compensation technique [17], the performance might be improved.…”
