摘要： An optical fiber is described in which the cladding is provided with a refractive index that increases in a radially outward direction. In particular embodiments the refractive index of the cladding increases monotonically from a low value to a value close to or higher than the refractive index of the core. Such a fiber can be formed that can be operated in an effective single mode manner or in multimode operation and which is very suitable for use in high-bit-rate communication systems.

摘要： An optical fiber is described in which a core is surrounded by a cladding having a refractive index that varies periodically in the angular sense around the core. By appropriate design of the cladding it is possible to provide an optical fiber capable of single-mode operation over a wide range of wavelengths with a large effective area.
