Abstract
Multicore fibers and methods are provided to reduce crosstalk between cores of the multicore fibers. Multicore fibers comprise a plurality of coated and/or cladded cores, which comprise an absorbing and/or scattering coating over a cladding of the core; and/or multilayered cladding comprising at least two cladding layers having different refractive indices. Imaging endoscopes may comprise the multicore fibers and be used for medical imaging.
Claims22
A multicore fiber comprising a plurality of coated and/or cladded cores, wherein the coated and/or cladded cores comprise at least one of:
- an absorbing and/or scattering coating over the core or over a cladding of the core;
- and/or
- multilayered cladding comprising at least two cladding layers having different refractive indices.
A multicore photonic crystal fiber with hollow cores, further comprising a plurality of absorbing and/or scattering rods surrounding the cores.
A method comprising reducing or eliminating crosstalk between cores of a multicore fiber comprising a plurality of coated and/or cladded cores, wherein the method comprises at least one of:
- applying an absorbing and/or scattering coating over claddings of the cores;
- and/or
- applying to the cores multilayered cladding comprising at least two cladding layers having different refractive indices.
