Abstract

Erbium-doped fiber amplifiers (EDFA) are now recognized as essential components for 1.5 μm optical fiber communications. An important characteristic of EDFAs is the amplified spontaneous emission (ASE), which provides useful information on its lasing characteristics. Some system applications require low-gain, distributed amplifiers for which characterization of unsaturated ASE noise features is useful.
