摘要： Various embodiments described herein relate to a laser source for producing a pulsed laser beam comprising a plurality of ultrashort optical pulses having a variable repetition rate. In one embodiment, the laser source comprises a fiber oscillator, which outputs optical pulses and a pulse stretcher disposed to receive the optical pulses. The optical pulses have an optical pulse width. The pulse stretcher has dispersion that increases the optical pulse width yielding stretched optical pulses. The laser source further comprises a fiber amplifier disposed to receive the stretched optical pulses. The fiber optical amplifier has gain so as to amplify the stretched optical pulses. The laser source includes an automatically adjustable grating compressor having dispersion that reduces the optical pulse width. The grating compressor automatically adjusts this dispersion for different repetition rates.

摘要： Optical gratings having a range of possible Bragg wavelengths can be produced using a single phase mask by exposing the mask to a non-collimated spatially filtered beam of light. A spatial filter (30) removes high spatial frequency components from the beam, and a focusing system (36) directs the filtered beam to a phase mask (40). A rate at which the beam is focused and a spacing between the phase mask and a photo-sensitive waveguide (12) are varied to produce gratings in the waveguide having a range of possible periods.

摘要： A bragg grating is made in an optical path composed of material exhibiting change in index when exposed to radiation of an actuating frequency by passing radiation from a source of such actuating frequency through a mask with periodic variation in transmission, phase, or other optical properties to expose the material of the path to a diffraction pattern.

摘要： A waveguide grating formation method comprises the steps of accelerating ions (IB); causing the accelerated ions to pass through a mask (16) having a shape corresponding to the grating; and implanting the ions (IB'), which have passed through the mask, into the core (3), to form refractive index-variation portions (4) for the grating in the core. The other formation method comprises the steps of accelerating ions, converging an ion beam formed of the accelerated ions, to make a beam diameter identical with or smaller than a width of refractive index-variation portions in a direction of the central axis of the optical waveguide so as to provide a converged ion beam (IB'); and intermittently irradiating the converged ion beam to the core (3), while moving an irradiation position in the direction of the central axis, to implant the ions into the core so as to form the refractive index-variation portions (4) in the core.

摘要： During the process of writing a grating, the fibre (F) is placed in a support (16) which has a surface cut-out such as a V-shaped groove (18). The side walls (20) of this groove (18) form an angle (α) of 60° with respect to the direction (X12) of propagation of the radiation arriving from the source (12). The aforesaid surfaces (20) have characteristics of high reflectivity with respect to the aforesaid radiation. Consequently, during the writing process, the core (1A) of the fibre (F) is subjected to the action of a plurality of radiation fronts converging on the core. The first radiation front corresponds to the radiation arriving from the source (12) and two other radiation fronts (B, C) are obtained from this radiation by the effect of the reflection from the walls (20) of the surface cut-out of the support (16). The preferred application is to the making of long-period gratings.
摘要翻译：在写入光栅的过程中，光纤（F）被放置在具有诸如V形凹槽（18）的表面切口的支撑件（16）中。该凹槽（18）的侧壁（20）相对于从源（12）到达的辐射的传播方向（X12）形成60°的角度（α）。上述表面（20）具有相对于上述辐射的高反射率的特性。因此，在写入过程中，纤维（F）的芯（1A）受到在芯上会聚的多个辐射前端的作用。第一辐射前部对应于从源极（12）到达的辐射，并且通过来自该辐射的表面切口的壁（20）的反射的效应从该辐射获得另外两个辐射前沿（B，C）支持（16）。优选的应用是制造长周期光栅。

摘要： A variable period amplitude grating mask (10) for use in making a long period Bragg grating is realized by a helically coiled spring (14). Stretching or compressing the spring changes the periodicity of the mask (10). A photosensitive optical waveguide (100), planar or fiber, is positioned within the spring coils (16) along the major axis of the spring (14). Actinic radiation is incident on the masked waveguide, and induces an index of perturbation in the waveguide having the periodicity of the mask. Different spring coil sizes and/or orientation of the waveguide respect to the mask provide linear or nonlinear (chirped) grating periods.

摘要： Techniques for fabrication of small-scale metallic structures such as microinductors, microtransformers and stents are described. A chemically active agent such as a catalyst is applied from an applicator in a pattern to an exterior surface of an article, metal is deposited according to the pattern and optionally, removed from the substrate. Where the substrate is cylindrical, the pattern can serve as a stent. Alternatively, a pattern of a self-assembled monolayer can be printed on a surface, which pattern can dictate metal plating or etching resulting in a patterned metal structure that can be cylindrical. In another embodiment, a structure is patterned on a surface that serves as a phase-modulating pattern or amplitude-modulating pattern. The article subsequently is exposed to radiation that can induce a change in refractive index within the article, and the phase-modulating or amplitude-modulating pattern results in different indices of refraction being created in different portions of the article. By this technique, a grating can be written into a core of an optical fiber.

摘要： Reducing the step size in a step and repeat process used to E-beam write field by field (11) a grating in a layer of resist (10) so that adjacent fields overlap, whereby two or more fields are employed to write each grating element, delocalises the stepping stitch errors, and thereby reduces their deleterious effect. The resulting increased writing complexity introduces other problems, and hence there is a limit beyond which further increasing the number of fields is no longer beneficial. By suitable grating of the irradiation dose in each field it has been found possible to increase further the delocalisation without further increasing the number of fields employed.
摘要翻译：在步骤中减小步长并重复用于电子束写入场的步骤（11）抗蚀剂层（10）中的光栅，使得相邻的场重叠，由此使用两个或更多个场来写入每个光栅元素，使步进针迹错误离域，从而降低其有害影响。所产生的增加的写作复杂性引入了其他问题，因此存在超出这一限度的范围，其中进一步增加字段的数量不再有益。通过在每个场中照射剂量的适当光栅，已经发现可以进一步增加离域，而不进一步增加使用的场数。
