    • A single mode optical fiber switch having a base (70) and a laterally slidable top (91). The base is composed of a quartz block (70) with a slight radius of curvature along its length supporting a silicon substrate (66) having a plurality of parallel v-grooves (68). The grooves are fitted with single mode optical fiber segments (64) and lapped to create a flat coupling surface (82) extending laterally across the base. The top (91) is composed of a quartz block with a single v-groove (93) holding a segment of single-mode fiber (95). This fiber (95) is lapped to create a flat coupling surface matable with the coupling surface on the base. The base (70) and top (91) are placed together such that the top fiber (95) may be selectively slid into and out of coupling alignment with any of the fibers (64) in the base (70) to form a discretely variable delay line. A single length of fiber (121) is wrapped around the base (70) in helical fashion with each loop being secured in one of the v-grooves (68). By coupling the top fiber (95) with different loops of the base fibers (121), different amounts of delay can be obtained. The delay line can be used to provide variable frequency response for notch and transversal filters.
    • 一种具有基座(70)和横向滑动顶部(91)的单模光纤开关。 基座由石英块(70)组成,石英块(70)沿其长度具有微小的曲率半径,支撑着具有多个平行的V形槽(68)的硅衬底(66)。 凹槽配有单模光纤段(64)并重叠,以形成横向延伸穿过底座的平坦的耦合表面(82)。 顶部(91)由具有保持单模光纤(95)的单个v形槽(93)的石英块组成。 该纤维(95)被研磨以产生可与基底上的联接表面配合的平坦的联接表面。 基部(70)和顶部(91)被放置在一起,使得顶部纤维(95)可以选择性地滑入和离开与基部(70)中的任何纤维(64)的联接对准,以形成离散变量 延迟线。 单个长度的纤维(121)以螺旋方式围绕基部(70)缠绕,每个环被固定在一个V形槽(68)中。 通过将顶部纤维(95)与基础纤维(121)的不同环耦合,可以获得不同的延迟量。 延迟线可用于为陷波和横向滤波器提供可变频率响应。

    • A continuously variable optical delay line having a first substrate (66, 70) and a second substrate (95). The first substrate is composed of a quartz block (70) with a large radius of curvature along its length, supporting a silicon substrate (66) having a plurality of longitudinal, parallel v-grooves (68). A single length (121) of single mode optical fiber is wrapped around the first substrate (66, 70) in helical fashion with each loop being secured in one of the v-grooves (68). The portions of the fiber (121) in the v-grooves (68) are lapped and polished to create a flat coupling surface extending laterally and longitudinally across the first substrate (66, 70). The second substrate (91) is composed of a quartz block with a single v-groove holding a segment of single mode fiber (95). The radius of curvature of this v-groove is substantially smaller than that of the first substrate, such that the flat coupling surface of the second substrate (91) is shorter than that of the first substrate (66). The first and second substrates are placed together such that the fiber in the second substrate is coupled to the fiber in the first substrate. By moving (142) the second substrate longitudinally with respect to the first substrate, a continuously variable delay can be obtained. The continuously variable delay line can be combined with a separate discretely variable delay line to create a longer continuous variable delay. The continuous variable delay line can be formed with only one v-groove (68) in the first substrate (66). fjdkfjdkfdjf
    • 一种具有第一基板(66,70)和第二基板(95)的连续可变光延迟线。 第一衬底由沿其长度具有大曲率半径的石英块(70)组成,支撑具有多个纵向平行V形槽(68)的硅衬底(66)。 单模光纤的单个长度(121)以螺旋方式缠绕在第一基板(66,70)周围,每个环固定在一个V形槽(68)中。 所述v形槽(68)中的所述纤维(121)的所述部分被研磨和抛光以产生横向和纵向延伸穿过所述第一衬底(66,70)的平坦的联接表面。 第二基板(91)由具有保持单模光纤(95)的单个v形槽的石英块组成。 该v形槽的曲率半径比第一衬底的曲率半径小,使得第二衬底(91)的平坦耦合表面比第一衬底(66)的平坦的耦合表面短。 将第一和第二基板放置在一起,使得第二基板中的光纤耦合到第一基板中的光纤。 通过相对于第一基板纵向移动(142)第二基板,可以获得连续可变的延迟。 连续可变延迟线可以与单独的离散可变延迟线组合以产生更长的连续可变延迟。 连续可变延迟线可以在第一基板(66)中仅形成一个V形槽(68)。 fjdkfjdkfdjf

    • Single mode, single polarisation fibres are produced by the introduction of anisotropy into an optical fibre of otherwise arbitrary geometry and arbitrary but guiding refractive index profiles. The anisotropy, which may be induced by the application of transverse stress to the optical fibre, is sufficient to establish conditions under which one mode of linearly polarised light "leaks" from the fibre. In the case of step-profile optical fibres, having a core (10) and a cladding (11), the anisotropy may be such that one mode of propagation of light is completely eliminated from the fibre. Alternatively, in such fibres, the anisotropy may be such that the leakage of the unwanted mode from the fibre is gradual, so that the fibre effectively attenuates that mode, thereby eliminating the propagation of that mode when the fibre has a sufficient length.
    • 单模式,通过将各向异性引入到任意几何形状和导向折射率分布的任意几何形状的光纤中来产生单极化光纤。 可能通过向光纤施加横向应力而引起的各向异性足以建立一种线性偏振光模式从纤维“泄漏”的条件。 在具有芯(10)和包层(11)的阶梯型光纤的情况下,各向异性可以使得从光纤中完全消除光的一种传播模式。 或者,在这样的纤维中,各向异性可以使得不需要的模式从纤维的泄漏是渐进的,使得光纤有效地衰减该模式,从而在纤维具有足够的长度时消除该模式的传播。
