  • Title: Measurement of optical waveguide scattering loss: an improved method by the use of a Coblentz mirror.
    Author: Wang H.
    Journal: Appl Opt; 1994 Mar 20; 33(9):1707-14. PubMed ID: 20885497.
    Abstract:
    Light scattered from optical waveguides is collected by a Coblentz mirror, which provides a stable, accurate, and relatively high signal-to-noise ratio measurement. The scattering loss of the waveguides is analyzed from the measured scattered-light-power distribution functions, and the results show that the attenuation coefficients of the waveguides can be expressed by the derivative of these scattered-light-power distribution functions, which can be calculated from a least-squares fit to the measured scattered-light-power distribution functions.
