Simulation and optimization of dielectric metalens with Tidy3D.

This repo contains an example of using Tidy3D to simulate and optimize a large area metalens.

Contents

Simulation Files

  • The jupyter notebook Metalens_Simulate_Single.ipynb runs the single simulation of a large area, 100 wavelength diameter metalens (with total dimensions of (100 x 100 x 46 wavelengths) in under 5 minutes.

  • The python script Metalens_Optimize.py runs a brute force optimization of the metalens unit cells to improve focusing efficiency by 10%.

Results and Post Processing

  • The colormap for plotting has data stored in BGYR_cmp.txt and is imported for plotting from cmap.py.

  • The data from the optimization runs are stored in data directory, as well as a script for potting this data.
