title: Bend loss in highly multimode fibres.
abstract: We investigate the bend loss of highly multimode air-clad microstructured polymer optical fibre which displays low bend loss for small bend radii. After repeated bending the loss approached a plateau, decreasing significantly after a characteristic length. The loss at a particular point depended on the configuration of the fibre preceding that point. A simple analytical model based on a transfer-matrix method is derived to explain this behaviour in terms of the power distribution amongst different mode groups. This model allows the effect of a particular fibre configuration to be predicted.
