摘要： Photodarkening in active fiber or waveguide devices (e.g. lasers, amplifiers, and incoherent sources such as ASE sources) can be reduced by altering the dopant concentration along the length of the doped fiber. A fiber or waveguide device includes two or more intentionally doped fiber or waveguide sections having different concentrations of one or more dopants. The dopants provide optical gain responsive to pump radiation provided to the fiber device by a pump source. A first optical intensity in a first of the fiber or waveguide sections is greater than a second optical intensity in a second of the fiber or waveguide sections. A first dopant concentration in the first fiber or waveguide section is lower than a second dopant concentration in the second fiber or waveguide section. Thus the dopant concentration is reduced in sections of the fiber or waveguide device having a higher optical intensity. The optical intensity can be due to pump radiation and/or signal radiation. Reduced dopant concentration in regions of high optical intensity reduces photodarkening.
摘要翻译：通过改变沿着掺杂光纤的长度的掺杂剂浓度，可以减少有源光纤或波导器件（例如，激光器，放大器和非相干源，例如ASE源）中的光标。光纤或波导器件包括具有不同浓度的一种或多种掺杂剂的两个或更多个有意掺杂的光纤或波导部分。掺杂剂通过泵浦源提供响应于提供给光纤装置的泵浦辐射的光学增益。第一光纤或波导部分中的第一光强度大于第二光纤或波导部分中的第二光强度。第一光纤或波导部分中的第一掺杂剂浓度低于第二光纤或波导部分中的第二掺杂剂浓度。因此，具有较高光强度的光纤或波导器件的部分的掺杂剂浓度降低。光强度可能是由于泵浦辐射和/或信号辐射。高光强度区域的掺杂剂浓度降低会降低光暗化。

摘要： The invention relates to an optical fiber as an optical waveguide for the single-mode operation. The present invention proposes a fiber having a microstructure, by which the propagation of modes of a higher order are selectively suppressed in the optical waveguide. At the same time, the propagation of transversal modes of a higher order is dampened more strongly than the propagation of the fundamental modes of the optical waveguide.
