Abstract
For the first time, the distributed gain along erbium-doped fibers was measured with high-resolution reflectometry. The coherent optical fre quency-domain reflectometry detection technique intrinsically filters amplified spontaneous emission, allowing precise measurements of Rayle igh backscattering levels and nondestructive determination of the opti mum length of the doped fiber for different pump and probe conditions.
