摘要： An optical fiber silica glass base material comprising a core formed of silica glass doped with a positive dopant that increases a refractive index; an intermediate layer adjacent to the core and surrounding the core on a radial outside thereof; a trench layer adjacent to the intermediate layer, surrounding the intermediate layer on a radial outside thereof, and formed of silica glass doped with a negative dopant that decreases a refractive index; and a cladding layer adjacent to the trench layer, surrounding the trench layer on a radial outside thereof, and formed of silica glass. Thickness of the intermediate layer in a radial direction is greater than thickness of the trench layer, and a region of the intermediate layer nearer the core is more heavily doped with the positive dopant and/or a region of the intermediate layer nearer the trench layer is more heavily doped with the negative dopant.

摘要： 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.
摘要翻译：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布置有包层特征的包覆材料的非常低的相对折射率差异。该相对折射率差可以由（n1-n2）/ n1表征，其中n1是其中包括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，而可提供模式滤波，单模传播和/或低弯曲损耗。

摘要： An optical fiber (12), which presents a beam expanding feature, has a core, an inner cladding, an outer cladding and a sheath. The inner cladding is doped with a photosensitive material like germanium. By using ultra-violet radiation (16) from a copper laser (18) having a Gaussian energy distribution, a refractive index taper may be created inside the fiber. Therefore the tapered fiber has a larger effective area in the coupling region (20), and insertion losses are reduced.
