Coupling Efficiency Analysis for Optical Fiber with Different Core Diameters

The loss of optical fiber link has a significant impact on the performance of optical fiber communication. In the short-distance optical interconnection, the quality of optical fiber connection is one of the main factors affecting the link loss, especially the influence of optical fiber coupling offset on the optical fiber coupling efficiency. In this paper, we build a model to quantitatively analyze the relationship between coupling offset and coupling efficiency. The simulation results show that a large core fiber has a higher tolerance to coupling offset compared with a traditional fiber.
