ABSTRACT:
An improved structure of an optical fiber having a core positioned in the center and a surrounding cladding with a lower refractive index than the core is disclosed. A tunnel extending in the axial direction of the optical fiber is provided in two diametrically opposite portions of the core-cladding interface. This fiber permits a single-polarized light to be transmitted only in a single mode.
