ABSTRACT:
An optical fiber having a core surrounded by a cladding layer which has an index of refraction less than the index of refraction of the core characterized by a longitudinal side coupling zone being formed by a longitudinal opening extending through the cladding layer of the fiber to expose a portion of the core. The optical fiber of the invention is particularly useful in conjunction with a light sensitive detector and is useful in a mixer where more than one fiber are joined together either in a bundle or in a strip configuration. The fiber with the side coupling zone can be formed by drawing the fiber from a workpiece having a core or rod member surrounded by a sleeve member or layer which is provided with the opening or can be drawn from a molten material utilizing a double crucible in which the opening of the inner crucible is provided with at least one bulge extending to the edge of the opening of the outer crucible.
