Fiber-based multi-resonator optical filters |
摘要 |
Optical filters comprising one or more optically-coupled Fabry-Perot resonators are disclosed. In some embodiments, the one or more optically coupled Fabry-Perot resonators include a graded index fiber. In some embodiments, the one or more optically coupled Fabry-Perot resonators are coupled end-to-end, whereas in other embodiments the one or more optically coupled Fabry-Perot resonators are side-coupled through evanescence. One or more implementations of an optical filter allow a spectral response of an input light beam to be controlled, through various approaches, e.g., by exposing a component fiber to ultra-violet radiation. |

1. An optical device, comprising:
a first fiber Fabry-Perot resonator comprising a first fiber segment, a first reflector formed on a first end facet of the first fiber segment and a second reflector formed on a second end facet of the first fiber segment; and a second fiber Fabry-Perot resonator optically coupled to the first fiber Fabry-Perot resonator, the second fiber Fabry-Perot resonator comprising a second fiber segment oriented to be parallel to the first fiber segment and located to have a portion that spatially overlaps with part of the first fiber segment and is optically evanescently coupled via sides of the first and second fiber segments to the first fiber segment, a third reflector formed on a first end facet of the second fiber segment and a fourth reflector formed on a second end facet of the second fiber segment, wherein a position of the second fiber segment can be shifted relative to the first fiber segment to adjust an interaction length for evanescent coupling between the first and second fiber segments. |
