Abstract

Sharp morphology-dependent resonance (MDR) peaks, observed in elastic and inelastic scattering spectra of fibers1 and dielectric spheres2,3 have been used to characterize the outer diameters of fibers1 and spheres.4,5 We use the algorithm developed by Hill et al:5 to determine the optical fiber diameter (≈125 μm) with approximately ±2-nm accuracy from the measured elastic spectra. Axially resolved spectra are used to measure the relative changes of the fiber diameter along the fiber axis with 8-nm accuracy.
