ABSTRACT:
According to the present invention the optical fiber includes a core with a first refractive index (n1) and the innermost core region with the refractive index n0, a cladding surrounding the core, the cladding having a third refractive index (n3), wherein n1>n3and n0<n1. According to some of the embodiments the optical fiber may also include a moat surrounding and abutting the core and situated between the core and the cladding, the moat having a second refractive index (n2), wherein n3>n2. It is preferable that at least one of the core, innermost core region and/or moat has a non-circular shape.
