Conducting electromagnetic wave analysis using the finite element method! Introducing a case study considering an L-shaped optical waveguide.
Photonic crystals are structures that can control light by periodically arranging multiple dielectrics. Electromagnetic wave analysis was conducted using the finite element method. The optical waveguide consists of periodically arranged dielectric rods, and light passes through the areas without dielectric rods. The radius of the rods, r, and the period of the rods, a, are set as r = 0.18a, and the electric field component parallel to the dielectric rods was input. 【Case Overview】 ■ Software Used: PHOTO-WAVEjω ■ Analysis Conditions - The radius of the rods, r, and the period of the rods, a, are set as r = 0.18a (Wavelength λ: 1.55μm, Refractive index n: 3.4) - Impedance boundary conditions are set on the sides - The electric field component parallel to the dielectric rods was input *For more details, please refer to the related links or feel free to contact us.

Company information
At Photon, we are developing "electromagnetic field analysis software" that models and simulates products and components utilizing electromagnetic phenomena on computers. In traditional design and development environments, the process has primarily revolved around trial and error through prototypes based on the experience of engineers and experiments with those prototypes. However, conducting experiments with actual prototypes and analyzing the results requires significant time and cost. Moving forward, transitioning from an experimental and prototype-based approach to an analysis-based design is a critical issue for improving productivity, and establishing simulation technology as the core of analysis-based design techniques is a challenge. In this context, Photon is developing and providing "analysis software" focusing on electromagnetic fields, as well as heat, vibration, and sound fields. By utilizing Photon’s software, efficient development and design of various industrial products can be achieved. In this way, Photon aims to reduce the number of prototypes and development costs, shorten development periods in the manufacturing sites of our users, and ultimately support the enhancement of our users' competitiveness.
