Assignee: LAWRENCE LIVERMORE NATIONAL SECURITY, LLC
Field: Optics (Instruments)
Classification: CPC H  G | IPC G  H

Claim 0:
1. An optical fiber, comprising:
a cladding;
a main core;
at least one side core having an index of refraction that is higher and a diameter that is smaller than that of said main core such that the modes of said at least one side core have an effective refractive index that varies faster with wavelength than the effective refractive index of modes of said main core, wherein said main core and said at least one side core are embedded within said cladding, wherein said at least one side core is located a distance from said main core such that the modes of said at least one side core and the modes of said main core hybridize into two supermodes having different dispersion than said modes of said main core and said modes of said at least one the side core, wherein when said main core and said at least one side core are placed in proximity, their modes hybridize around the wavelength at which their effective indices coincide, yielding supermodes with qualitatively different dispersion compared to the modes of said main core and said at least one side core isolated one from another; and
a secondary cladding surrounding said cladding.
