VFEM Accuracy and Advantages

As optical systems move towards an integrated platform, the modelling of high refractive index contrast, sub-wavelength dimension…

Plasmonic Arrays

Plasmonic nano-hole arrays are an interesting avenue of research because of their highly sensitive transmission properties. Incorporating the already strong light-matter interaction of surface plasmons into a periodic structure allows…

Surface Plasmon

Suface Plasmon

Surface plasmons are waves that propagate along the surface of metallic and certain dielectric materials. The electric field of a plasmon wave reaches its maximum at the surface and decays evanescently away from the surface. The wave properties are highly sensitive to any changes in the refractive index of the material as well as the device’s geometry. As a full wave modeling method…

Diffraction Grating

Finite-Difference Time-Domain (FDTD) is a powerful numerical method for simulating diffraction gratings, where the grating element and working wavelength are close in size. With OptiFDTD, the incident wave can be versatile and best matched with the real application; the CAD tools enable us to design different types of grating layouts; the simulated near field pattern…

Photonic Crystal

OptiFDTD provides two simulation engines for modeling photonic crystal devices and corresponding defects: 1) 2D and 3D FDTD simulation to study the field response and transmission/reflection spectrum; 2) PWE method to perform ban-diagram analysis for 1D, 2D and 3D photonic crystal devices.

Optical FDTD Overview

OptiFDTD enables you to design, analyze and test modern passive and nonlinear photonic components for wave propagation, scattering, reflection, diffraction, polarization and nonlinear phenomena…
