  • Abstract
    The measured attenuation coefficient of the LP11 modes in curved optical fibers for various radii of curvature in the wavelength region below the cutoff wavelength for LP11 modes is discussed. The experimental results indicate that the attenuation coefficient may be strongly enhanced at certain wavelengths due to phase-matched coupling between the LP11 modes of the fiber core and whispering gallery modes of cladding. Implications for measurements of the effective cutoff wavelength in optical fibers are discussed
