Abstract
The attenuation properties of Co2+-doped single-mode optical fibers were ex perimentally and analytically investigated for preparation of a stable flat band attenuator. By controlling the Co2+-doped region in a fiber core, we c ould prepare a flatband attenuator in which the attenuation in wavelengths 1530-1610 nm was held to within 9.9-10.2 dB (3% variation) and the fluctuat ion of attenuation was less than 0.1 dB with 1-W input power for 100 h.
