Lumerical FDTD Note for Optical Simulation

2019-05-30 /

Here talking about how to do Optical Diffraction Simulation by Lumerical FDTD software. Here Only write some text, maybe I will prepare more detail to clearly explain in future.

What’s FDTD?

FDTD is a simulator within Lumerical’s DEVICE Multiphysics Simulation Suite, the world’s first multiphysics suite purpose-built for photonics designers. The DEVICE Suite enables designers to accurately model components where the complex interaction of optical, electronic, and thermal phenomena is critical to performance.

1. Open FDTD

  • Initial project is 3D project

2. Add Simulation Region

  • Background index
  • Geometry
  • Mesh settings
  • Boundary conditions
  • z direction use PML
  • x, y direction use Periodic

if want to simulate tilt angle light sourse (like SA)
we must use Bloch

3. Add Structure

  • Geometry
  • Material index
  • Rotations

4. Add Source

  • General
  • Plane wave

  • angle, direction

  • Geometry

  • Wavelength

5. Add Monitor

  • Refractive index
  • Movie
  • Refractive index

6. loop

  • sweep
