Conducting electromagnetic wave analysis using the finite element method! Introducing a case study of an L-shaped optical waveguide.
Photonic crystals are structures that can control light by periodically arranging multiple dielectrics and other materials. Electromagnetic wave analysis was conducted using the finite element method. The optical waveguide consists of periodically arranged dielectric rods, and light passes through areas where there are no 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 a computer. In traditional design and development environments, the process has primarily revolved around trial and error through prototyping based on the experience of engineers and experiments with prototypes. However, conducting experiments using actual prototypes and analyzing the results requires significant time and cost. Moving forward, transitioning from an experimental and prototyping-based approach to an analysis-based design approach will be a crucial challenge for improving productivity, and establishing simulation technology as the core of analysis-based design techniques will be essential. 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 support users in reducing the number of prototypes, lowering development costs, and shortening development periods in their manufacturing environments, ultimately enhancing their competitiveness.
