摘要： An optical fibre that use index-guidance formed with a low index cladding or a microstructured cladding using voids/holes or low index features (404) together with multiple high index resonant cladding features (1205, 1206). One to three resonant cross sectional extending structure act as a filter by resonantly coupling light out to part of the cladding (1202) or other structures (fx. a high index outer cladding ring) that acts as light sink(s) at one to three wavelength when using one to three materials or features with different size, shape, refractive index profile or normalized frequency parameter. The fibre can be asymmetrical. The fibre can be adapted for suppression of higher order modes (HOM) and/or guiding light in a narrow spectral wavelength range and act as a band pass filter. For enhancing out-coupling the high index features can be arranged along two intersecting lines tangentially positioned in relation to the core and along a line that extends from the core and intersects the tangentially positioned lines. Light absorbing material such as samarium can be used in the light sink. The fibre can be used in a fibre amplifier or fiber laser.

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。

摘要： Included among the many structures described herein are photonic bandgap fibers designed to provide a desired dispersion spectrum. Additionally, designs for achieving wide transmission bands and lower transmission loss are also discussed. For example, in some fiber designs, smaller dimensions of high index material in the cladding and large core size provide small flat dispersion over a wide spectral range. In other examples, the thickness of the high index ring-shaped region closest to the core has sufficiently large dimensions to provide negative dispersion or zero dispersion at a desired wavelength. Additionally, low index cladding features distributed along concentric rings or circles may be used for achieving wide bandgaps.
