Abstract

Noise figure reduction of an erbium-doped fiber amplifier using loop mirror filter is demonstrated. Approximately 0.5-dB noise figure reduction is achieved at input signal power level below - 30dBm. Transferring energy from the amplifier spontaneous emission to the input signal compensates for the insertion loss of the loop mirror filter device. The insertion loss of the device approximately 1 dB.

Abstract

A comprehensive study of implementing erbium-doped fiber amplifiers (EDFAs) using a loop configuration is presented. Two different schemes based on the mechanism of directing the loop output are investigated. The amplified spontaneous emission at the output port is 3 dB lower than conventional designs. This configuration is recommended for high-power EDFAs.
