A radiation-temperature coupling model of the optical fiber attenuation spectrum in the Ge/P co-doped fiber

Abstract

Abstract The radiation-temperature coupling model of the optical fiber attenuation spectrum has been developed. The spectrum in Ge/P co-doped fiber ranging from 800 nm to 1600 nm at different temperatures and doses were measured and decomposed according to the configurational coordinate model. Based on which the power law model is employed to predict the intensity of color center absorption band at different doses. And the fiber loss in space was predicted the model. This work will benefit the application of fibers in the complicated radiation environment.
