Abstract
Angular- and spectral-light-scattering measurements have been made for a glass fiber parallel to and at varying distances from a mirror. Scattering calculations have been made for two parallel fibers. The multiple-scattering effects between a fiber and its mirror image or between two fibers are shown to be quite similar, even for an imperfectly conducting mirror. The multiple scattering becomes less important when one fiber is not in the shadow of the other and when the separation is large. Also, the morphology-dependent resonances shift, and the line shapes change as the separation decreases. In the fiber–mirror configuration, the evanescent fields of the fiber couple to propagating surface plasmons of the metal mirror for TE polarization, greatly damping the scattered intensity.
