Preform for an Optical Waveguide and A Fiber with Non-Circular Core

Preform for an Optical Waveguide and A Fiber with Non-Circular Core

Preform for an optical waveguide containing a core with a non-circular geometry and at least one cladding layer, in which the dopand concentration of the cladding layer is increased compared to the dopand concentration of a preform with circular core geometry and identical NA. A method for the produ...

Zusammenfassung:Preform for an optical waveguide containing a core with a non-circular geometry and at least one cladding layer, in which the dopand concentration of the cladding layer is increased compared to the dopand concentration of a preform with circular core geometry and identical NA. A method for the production of a preform for an optical fiber is provided. An optical waveguide with a nominal dopand concentration of c(eff) x F c(nom) in at least one cladding layer is also provided.
