Novel Measurement-Based Efficient Computational Approach to Modeling Optical Power Transmission in Step-Index Polymer Optical Fiber

Polymer optical fibers (POFs) are playing an important role in industrial applications nowadays due to their ease of handling and resilience bending environmental effects. A POF can tolerate a radius less than 20 mm, it work environments with temperatures ranging from −55 °C +105 °C, its lifetime is around years. In this paper, we propose novel, rigorous, efficient computational model estimate the most parameters that determine characteristics light propagation through step-index polymer fiber (SI-POF). The uses attenuation, diffusion, mode group delay as functions angle characterize power transmission SI-POF. Taking into consideration allows us generalize be applicable POFs different index profiles. particular, use experimental measurements spatial distributions frequency responses derive accurate for our SI-POF simulation model. data were measured at lengths according cut-back method. This method consists taking several such responses, angular intensity distributions, over long length (>100 m), then cutting back while maintaining same launching conditions repeating on shorter fiber. derivation objective function minimize differences between simulated results. matrix exponential (MEM) implement results computationally suitable POF-based system-level studies. efficiency gain independence calculation time respect length, contrast classic analytical solutions time-dependent flow equation. robustness proposed validated by calculating goodness-of-fit predictions relative data.
