| 摘要 | A spacecraft or satellite optical transmission apparatus (10) including an optical fiber (11) and at least one optical pump source (14) operatively coupled to provide pump energy to the optical fiber (11), the optical fiber (11) comprising an active trivalent dopant such as erbium and at least one passive trivalent dopant such as lanthanum. A method for transmitting electromagnetic radiation in a high radiation environment is also disclosed. | ||

| 主权项 | 1. An optical transmission apparatus, comprising: an optical fiber having a core including an active trivalent dopant and at least one passive trivalent dopant; and, at least one optical pump source operatively coupled to provide pump energy to the optical fiber at a frequency between 800 and 1,100 nm, the pump energy cooperative with the active and passive dopants to accelerate photo-annealing of radiation damage in the optical fiber. | ||
