摘要： Various embodiments described herein comprise a laser and/or an amplifier system including a doped gain fiber (1404) having ytterbium ions in a phosphosilicate glass. Various embodiments described herein increase pump absorption to at least about 1000 dB/m - 9000 dB/m. The use of these gain fibers provide for increased peak -powers and/or pulse energies. The various embodiments of the doped gain fiber (1404) having ytterbium ions in a phosphosilicate glass exhibit reduced photo-darkening levels compared to photo-darkening levels obtainable with equivalent doping levels of an ytterbium doped silica fiber.

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 (ni-n2)/ni, where ni 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 x 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： 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.

摘要： One or more single mode few-moded or multimode fibers are incorporated into a bundle to carry input to a fiber amplifier or output from a fiber amplifier or a fiber laser. The input is at the signal wavelength, which is the wavelength where amplification or lasing occurs. Each of the fibers in the bundle is cleaved individually or as a group and fiber ends are aligned in the same plane. The fiber amplifier or fiber laser may include a double clad fiber and the other fibers of the bundle couple light for cladding pumping. The device may also include a mode filter for controlling the output mode.

摘要： Various types of holey fiber provide optical propagation. In various embodiments, for example, a large core holey fiber comprises a cladding region formed by large holes arranged in few layers. The number of layers or rows of holes about the large core can be used to coarse tune the leakage losses of the fundamental and higher modes of a signal, thereby allowing the non-fundamental modes to be substantially eliminated by leakage over a given length of fiber. Fine tuning of leakage losses can be performed by adjusting the hole dimension and/or the hole spacing to yield a desired operation with a desired leakage loss of the fundamental mode. Resulting holely fibers have a large hole dimension and spacing, and thus a large core, when compared to traditional fibers and conventional fibers that propagate a single mode. Other loss mechanisms, such as bend loss and modal spacing can be utilized for selected modes of operation of holey fibers. Other embodiments are also provided.
摘要翻译：各种有孔光纤提供光学传播。在各种实施例中，例如，大的核心多孔纤维包括由几层布置的大孔形成的包层区域。可以使用围绕大芯的多个层或多排的孔来粗调基本信号和较高模式的信号的泄漏损耗，从而通过在给定长度的光纤上的泄漏来基本上消除非基本模式。泄漏损失的微调可以通过调整孔尺寸和/或孔间距来实现，以产生所需的基本模式的泄漏损失的操作。与传统单模式的传统纤维和传统纤维相比，所产生的多孔纤维具有较大的孔尺寸和间距，因此具有较大的纤芯。诸如弯曲损耗和模态间隔的其它损耗机制可以用于多孔纤维的选定操作模式。还提供了其他实施例。

摘要： A method for producing three-dimensional space frames or truss structures from simpler components and space frames or truss structures produced by the associated method. The various components, which may be made from virtually any material, are shaped in such a way so that they may be fitted together to create a space frame or truss structure. The components may be held together by any available attachment means, or by the interaction of the components themselves. The method and associated components allows for the assembly of three-dimensional space frames or truss structures from planar materials, significantly reducing cost and manufacturing time. These space frames or trusses can then be used as structural members, as the interior load-bearing portions of sandwich panels, or in any situation where high-strength and light weight are desirable.
