Reducing pulse distortion in fast light pulse propagation by Pulse-on-Background method through an erbium-doped fiber amplifier

Abstract

A novel method (Pulse-on-Background) to reduce pulse distortion in fast light pulse propagation through an erbium-doped fiber amplifier by adding a background of appropriate power is suggested. The Pulse-on-Background method depends on pulse width, pump power, pulse power and background-to-pulse power ratio.
