OPTICAL FIBER WITH MOSAIC FIBER

摘要

An optical fiber includes a monolithic elongated mosaic core having a longitudinal axis and configured with a silica-based medium with a uniform refractive index, and a plurality of coaxial elongated individual elements which do not waveguide light at a given wavelength and are received in the silica-glass medium. The refractive indices of the medium and individual anti- waveguiding elements together determine a cumulative effective refractive index of the mosaic core. The optical fiber further includes at least one cladding surrounding the mosaic core and provided with a cladding refractive index which is lower than the index of the mosaic core, so that the mosaic core waveguides the light at the given wavelength.

1. An optical fiber, comprising:
an elongated mosaic core having a longitudinal axis and comprising a plurality of elongated individual elements each inhibiting propagation of light at a given wavelength, the individual elements being bundled together and having respective refractive indices which together determine a cumulative refractive index of the mosaic core; and at least one cladding surrounding the mosaic core and provided with a cladding refractive index which is lower than the cumulative refractive index of the mosaic core so that the mosaic core is capable of waveguiding the light at the given wavelength,wherein the refractive indices of respective mosaic core and cladding are controllably selected to define a predetermined refractive index profile of the optical fiber.
