Technical Examples
  1. The present invention provides a method and resulting device for producing a low-loss spectrally periodic all fiber filter by providing a multi-mode fiber capable of propagating an LP01 mode and an LP02 mode at wavelengths of interest and providing a single-mode fiber capable of propagating a fundamental mode at the wavelengths of interest and splicing a selected length of the multi-mode fiber between lengths of the single-mode fiber, where the properties of the multi-mode fiber and the single-mode fiber are related such that the optical field distribution resulting from the coherent superposition of the optical field of the LP01 mode and the optical field of the LP02 mode in the multi-mode fiber is sufficiently similar to the optical field distribution of the fundamental mode in the single-mode fiber at the wavelengths of interest, such that transmission across the two splices taken together at the wavelengths of interests is at least 70%, desirably at least 80% and most desirably at least 90%, and the extinction ratio of the filter is at least 10 dB. The method may also include the step of monitoring light passing through the spliced length of the multi-mode fiber while tapering the multi-mode fiber to adjust the spectral profile of the resulting filter.
