Simulation Description

Most photonic crystals have a periodic lattice, which allows users to reduce the simulation size by using plane wave excitation and PBC boundary conditions. During simulation, the real-time propagation can be viewed in both 2D and 3D.

The diagram below shows the 3D wave propagation.

FDTD - 3D Wave propagation

Observation points can be analyzed in real-time. Below is the reflected electric field in black and the transmitted field in blue.

FDTD - Reflected electric field in black and transmitted field

After simulation, transmission and reflection functions can be plotted.

FDTD - Transmission and reflection functions

PWE Bandsolver

Allows users to identify band gaps that exist within the photonic crystal structure. The band solver works in either 1, 2, or 3-dimensions.

The diagram below is a graph populated with a set of eigen-frequencies provide a clear picture of the band diagram allowing users to identify band gaps.
