中文摘要

An experimental and numerical investigation is performed into the power loss
induced in grooved polymer optical fibers (POFs) subjected to combined bending and
elongation deformations. The power loss is examined as a function of both the groove
depth and the bend radius. An elastic-plastic three-dimensional finite element model is
constructed to simulate the deformation in the grooved region of the deformed specimens. The results indicate that the power loss increases significantly with an increasing bending displacement or groove depth. Specifically, the power loss increases to as much as 12% given a groove depth of 1.1 mm and a bending displacement of 10 mm. Based on the experimental results, an empirical expression is formulated to relate the power loss with the bending displacement for a given groove depth. It is shown that the difference between the estimated power loss and the actual power loss is less than 2%.
