Abstract

A theoretical model has been developed to describe the bend loss characteristic of buffered single-mode optical fiber, based on interference between the core-guided mode and a 'whispering gallery' mode guided in the buffer coating. The theory is supported by experiments in which the relative phase of the modes was modulated by temperature or wavelength. As the arc length of the bend is increased, multiple-order interference is observed and predicted. The model was extended to over-moded fibers, and was consistent with experiments demonstrating coupling between the LP₁₁ and a whispering gallery mode.
