Abstract: Embodiments of optical fiber may include cladding features that include a material (e.g., fluorine-doped silica glass) that may produce a very low relative refractive index difference with respect to cladding material in which the cladding features are disposed. This relative refractive index difference may be characterized by (n1−n2)/n1, where n1 is the index of refraction of the cladding material in which the cladding features are included, and n2 is the index of refraction of the cladding features. In certain embodiments, the relative refractive index difference may be less than about 4.5×10−3. In various embodiments, the configuration of the cladding features including, for example, the size and spacing of the cladding features, can be selected to provide for confinement of the fundamental mode yet leakage for the second mode and higher modes, which may provide mode filtering, single mode propagation, and/or low bend loss.
Abstract translation: 光纤的实施例可以包括包括材料（例如氟掺杂石英玻璃）的包层特征，其可以产生相对于其中设置包层特征的包层材料的非常低的相对折射率差。 该相对折射率差可以由（n1-n2）/ n1表征，其中n1是其中包含包层特征的包层材料的折射率，n2是包层特征的折射率。 在某些实施方案中，相对折射率差可以小于约4.5×10 -3。 在各种实施例中，可以选择包括例如包层特征的尺寸和间隔的包层特征的配置，以提供用于第二模式和更高模式的基模模式的限制，而这可以提供模式滤波 ，单模传播和/或低弯曲损耗。

Abstract: Various embodiments described herein include rare earth doped glass compositions that may be used in optical fiber and rods having large core sizes. Such optical fibers and rods may be employed in fiber lasers and amplifiers. The index of refraction of the glass may be substantially uniform and may be close to that of silica in some embodiments. Possible advantages to such features include reduction of formation of additional waveguides within the core, which becomes increasingly a problem with larger core sizes.
