Abstract

        Inthis paper, we analyse the bending loss of step-index plastic optical fiber (POF) using geometric approach. The radiation loss only occurs at reflection points, and can be described by the power-transmission coefficient T which is different for tunneling and refracting rays. A numerical simulation shows that the bending loss of step-index POF becomes larger as the curve radius is less than 20mm. This result is helpful to design a mode scrambler which is used in step-index POF measurements.
