Suface Plasmon

Surface 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…

FDTD - Diffraction Grating 3D Layouts

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…

FDTD - Photonic Crystal Layout

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.
