Abstract

The attenuation properties of Co2+ -doped single-mode optical fibers were experimentally and analytically investigated for preparation of a stable flatband attenuator. By controlling the Co2+ -doped region in a fiber core, we could 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 fluctuation of attenuation was less than 0.1 dB with 1-W input power for 100 h.
