Using the self-organized lightwave network (SOLNET) technique, we observed guided beam leakage and scattering at tapered mirrors of core end facets in optical waveguide Alms. The leakage/scattering are caused by the tunneling of guided beams into the cladding film and pattern imperfection of core ed...
