Physical-Optics-Based Tolerance Analysis for Fiber Coupling Systems

San Diego, 12 August, 2019, SPIE - Optics & Photonics - Optical Modelling and System Alignment

The use of fibers helps reduce the size of optical system and makes the interconnection between systems convenient. But on the other side, the design and analysis of systems containing fibers often go beyond traditional ray-optics modeling. Because the interaction between light and fibers, with core diameter only several micrometers, requires electromagnetic field solvers. In this work, we present a physical-optics-based modeling technique for the complete optical system, including large-scale lenses and micro-scaled optical fibers.
