It is reported for the first time that refractive indices are reduced remarkably by residual stress in undoped silica-core/fluorine-doped silica-clad single-mode fibers. The very high residual stress concentrated at the small diameter core is induced by drawing tension because of the difference in viscosity between the core and cladding. The decrease in refractive indices results from photoelastic effects due to residual stress in the core.
