Multi-channel power-equalizing reflective erbium-doped fiber amplifier

Multi-channel power-equalizing reflective erbium-doped fiber amplifier
Multi-channel power-equalizing reflective erbium-doped fiber amplifier
Power-equalizing erbium-doped fiber amplifiers (EDFAs) counteract detrimental spread of channel-powers in wavelength-division multiplexed transmission. Unfortunately, because of the homogeneously broadened gain-spectra of Er-doped fibers (EDFs) at room temperature, power-equalization is difficult in EDFAs. However, if different channels travel different paths through the amplifier, the gain becomes effectively inhomogeneously broadened thus facilitating equalization. We propose and numerically analyze a new reflective EDFA in which different channels travel partly different paths by virtue of different points of reflection. This can then equalize channel powers without any complex adjustable filters or control circuits.

Abstract

Power-equalizing erbium-doped fiber amplifiers (EDFAs) counteract detrimental spread of channel-powers in wavelength-division multiplexed transmission. Unfortunately, because of the homogeneously broadened gain-spectra of Er-doped fibers (EDFs) at room temperature, power-equalization is difficult in EDFAs. However, if different channels travel different paths through the amplifier, the gain becomes effectively inhomogeneously broadened thus facilitating equalization. We propose and numerically analyze a new reflective EDFA in which different channels travel partly different paths by virtue of different points of reflection. This can then equalize channel powers without any complex adjustable filters or control circuits.
