Abstract

An experimental investigation is presented on the conditions affecting the measurement of waveguide loss by detection of scattered radiation. Several factors have been taken into account, including: numerical aperture, magnification, defocusing and spatial resolution of the optical collection system; presence of spurious background; direction of collection and shape of the scattering lobe; mode-selective measurements. Measurements have been made at visible and near-IR wavelengths on planar and stripe waveguides, single- and multi-moded, and results on the best measurement conditions are reported.
