In this video, we demonstrate a step-by-step simulation of Single Mode Optical Fiber using COMSOL Multiphysics. You'll learn how to model the fiber structure, set up boundary conditions, select appropriate physics (like Electromagnetic Waves, Frequency Domain), and analyze mode. This article demonstrates the use of several fiber coupling efficiency analyses in OpticStudio. The tutorial has the following parts: In the previous part, we have seen that depending on its refractive index profile and the wavelength, a fiber may guide different numbers of modes. Among the wide variety of fibers that exist, one important categorization criterion is if the fiber is multimode or single mode. To define a fiber profile, follow these steps: From the “File” menu click “New” to open a new project.
