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 losses between 60 and 70 dB/km, have permitted the measurement of bending losses which become dominant at radii of curvature of a few centimeters. An approximate theory based on bending a rectangular guide appears to represent the circular waveguide results very well. 
Attenuation of multimode glass optical waveguides
Glass optical waveguides show great promise of being the transmission medium for optical communication links. Single‐mode waveguides have already been reported having a total attenuation of less thanExpand
New low-loss liquid-core fibre waveguide
Low-loss liquid-core fibre-optical waveguides having a transmission loss of 10 dB/km has been made using commercially available glass tubing. The loss is less than 20 dB/km over a wavelength range ofExpand
Pulse transmission through a dielectric optical waveguide.
Waveguide propagation of a pulse-modulated carrier wave is formulated to include distortion due to dispersion in both attentuation and phase velocity. An optimum input gaussian pulse width exists forExpand
Spectral response of low-loss optical waveguides.
Independent attenuation measurements from 600 nm to 1060 nm have been made on low-loss waveguides and bulk cladding glass, using both laser and scanning-prism monochromator sources, and assumptions too small to be precisely measured in the bulk glass measured in them. Expand
Birefringence in dielectric optical waveguides
The linear and circular birefringent properties of low-loss single-mode glass fibers are found to depend upon length. Depolarization is about 1 percent/km. Some anomalous behavior can be explained inExpand
Modes in weakly guiding elliptical optical fibres
Approximate and much simplified dispersion relations are obtained for the problem of optical wave propagation within weakly guiding elliptical fibres. The refractive index difference between the coreExpand
Tube waveguide for optical transmission
The dielectric optical waveguide described in this paper has an annular cross section, the refractive index of which is higher than the indices of the material inside and outside of the ring. TheExpand

The measurement of the angular distribution of light scattered from a low-loss fiber at 1.06 microm and 0.633 microm shows Rayleigh scattering, and a previously undetected, near-forward scattering peak was observed. Expand

Simple formulas and functions for the fiber parameters are presented as a help for practical design work that considers the propagation constant, mode delay, the cladding field depth, and the power distribution in the fiber cross section. Expand
Modes of optical waveguides
A simple method is presented for finding the modes on those optical waveguides with a cladding refractive index that differs only slightly from the refractive index of the core. The method applies toExpand


Mode conversion caused by diameter changes of a round dielectric waveguide
This paper presents the theory of mode conversion and radiation losses of the lowest order circular electric mode in a dielectric rod (fiber) waveguide and its confirmation by a microwave experiment.Expand
Improved relations describing directional control in electromagnetic wave guidance
The direction-changing capability of electromagnetic waveguides may be limited not only by mode conversion but also by radiation if the transverse field extends indefinitely into a freely propagatingExpand
Excitation and Scattering of Modes on a Dielectric or Optical Fiber
A technique similar to that of Kirchhoff is used to obtain an analytic expression for mode Iaunching on a semi-infinite rod. The approximation is quasi-optical and only valid for small angles ofExpand
Light Scattering by Glasses
Previous light scattering investigations have shown that glasses contain inhomogeneities other than density fluctuations from room temperature agitation. These inhomogeneities were investigated byExpand
