title: Bend-induced loss for the higher-order spatial mode in a dual-mode fiber.
abstract: Measured loss for the LP(11) mode in a dual-mode fiber subjected to a uniform bend shows a strong dependence on the orientation of the mode-field pattern relative to the plane of the fiber bend. Wavelength and bend-radius dependence of the loss indicates that operation within ~40 nm of cutoff is feasible in dispersion compensators based on dual-mode fibers operated in the LP(11) spatial mode near cutoff.
