| 英文摘要 | 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 |
