Diffraction Grating

Modelling diffraction gratings with an oblique incidence

Real parts of the Ex and Ez components of the near field; note that these fields are pseudo-periodic i.e. periodic with a phase shift

Gratings with RCWA

For simulation of infinitely periodic gratings

Real-time visualisation of the fields during the FETD simulation for a different tilt angle of +5 degrees; you can see the adaptive triangular mesh of the FETD Engine superimposed over the fields.

Surface Grating Coupler

For modelling a vertical grating structure

Our Heritage in Crystals

OmniSim started life as CrystalWave, an FDTD tool for specifically simulating crystals and waveguides made by crystal defects. As its functionality grew to general waveguide simulations, plasmonics, and more, CrystalWave became OmniSim. OmniSim continues to serve those designing crystals with a uniquely extensive array of UI tools for quickly designing large repeating crystals and modules such as the Band Analyser.
