title: LP(11) mode loss measurements in the two-mode-propagation region of optical fibers.
abstract: We propose a new method of separately measuring the LP(01) and LP(11) mode losses in the two-mode-propagation region of optical fibers. It is found that LP(11) mode loss measured by this technique rapidly increases as the wavelength approaches the effective cutoff wavelength, while the LP(01) mode loss shows the expected Rayleigh scattering loss versus wavelength.
