| 摘要 |
A spacecraft or satellite optical transmission apparatus 10 includes 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 has an active trivalent dopant such as erbium and at least one passive trivalent dopant such as lanthanum, aluminium or phosphorus. The apparatus is designed to be resistant to hazardous radiation in the form of solar particle events (SPEs) and galactic cosmic rays (GCR) encountered in deep space. The active and passive dopants may form a trivalent matrix. The apparatus may also be used for transmitting electromagnetic radiation in a high radiation environment such as a nuclear reactor facility or near a high energy physics (HEP) apparatus. |
