RADIATION LOSSES IN GLASS OPTICAL WAVEGUIDES
Measurements show that single‐mode waveguides can be constructed which have radiation losses of about 7 dB/km—very close to the intrinsic material scattering loss. These waveguides, with total lossesExpand
On the ultimate lower limit of attenuation in glass optical waveguides
The fabrication of an extremely‐low‐loss glass optical waveguide, having as little as 4 dB/km total attenuation, has allowed interpretation of the absorption spectrum to a much greater degree thanExpand
Crystal Nucleation in a Glass Containing Titania
The mechanism of crystal nucleation in a titania‐magnesia‐alumina‐silica glass has been studied by light scattering. Predominantly isotropic scattering centers become anisotropic during the initialExpand
Glass fibers for optical communications
Glass optical waveguides with attenuations below 20 dB/km have made possible a new approach to optical communications. These glass fibers satisfy requirements for transmission over kilometer lengthsExpand
Pressure Effects in the Transformation Range of Glass
Survey experiments have been made to find the effect of pressure on relaxation rates and volume in the transformation range of glass. An empirical equation used to describe relaxation effects forExpand
Effect of neutron- and gamma-radiation on glass optical waveguides.
Multimode glass optical waveguides with very low attenuation have been made by laboratory techniques. A desirable property of optical waveguides is the resistance to the environmental hazard ofExpand
Tensile strength and fatigue of optical fibers
A method is presented for analyzing laboratory measurements of tensile strength and fatigue failure rates of glass fibers. This method provides the physical basis for extrapolating laboratory data toExpand
Theory of backscattering effects in waveguides.
Associated with a signal transmitted down a waveguide are multiple back and forth scatterings. These produce a delayed decaying interference trailing a sharp signal pulse. An analytical descriptionExpand
