ABSTRACT:
A single-mode optical fiber that includes: (a) a core that includes silica and is characterized by a first refractivity that changes upon exposure to actinic radiation of a predetermined wavelength; and (b) a cladding surrounding the core that also includes silica and is characterized by a second refractivity different from the first refractivity that changes upon exposure to actinic radiation of a predetermined wavelength. At least one of the core and the cladding further includes boron, the relative amounts of boron in the core and cladding being selected such that the first refractivity and the second refractivity change by substantially the same amount upon exposure to actinic radiation of a predetermined wavelength.
