Abstract

An optical waveguide (10), such as an optical fiber, having a cladding (12) and a core (14), is provided with a bulge (16) of the outer dimension over a predetermined length L of the waveguide (10). The cladding may also have an outer buffer layer (18). The bulge (16) provides a low-creep high-strength means for attaching the fiber (10) to a structure, e.g., for use in an optical sensor. Also, the fiber (10) with the bulge (16) exhibits low optical loss of light propagating in the core (14) through the bulge (16) and good mechanical strength.
