OPTICAL FIBER AND MANUFACTURE THEREOF

Title:

OPTICAL FIBER AND MANUFACTURE THEREOF

Document Type and Number:

Japanese Patent JPS58114004

Kind Code:

A

Abstract:

Selected portions of the interior surface of a substrate tube, or of the cladding or core layers deposited on the interior surface of the substrate tube, are treated by one or more process steps such as shaping, diffusing, leaching, or depositing. Patterning processes such as photolithography and lift-off are employed to define the selected portions. The resulting core and/or cladding layers of the fiber can be made to have a variety of geometric shapes and composition profiles useful, for example, in realizing birefringent fibers and multiple-core fibers. Also described is the similar treating of metal layers and the incorporation of such layers into the fiber.
