Getting Started¶
Hello World Program¶
To run a simple example, run:
This should run an example with a 10-layer bragg mirror (also known as a [dielectric mirror](https://en.wikipedia.org/wiki/Dielectric_mirror)), which can have very high reflectance near its design wavelength, and output the reflectance and transmission as a function of wavelength.
2D Photonic Crystal Example¶
The examples folder also contains a 2D photonic crystal example called triangular_photonic_crystal.py. Running it will print the reflection and transmission coefficients, but diving into the example you can extract any quantities of interest: amplitude reflection coefficients, diffraction efficiencies for each harmonic, etc.
Features¶
- Implements 1D Transfer Matrix Method for homogenous layers
- Implements full rectangular 2D RCWA for periodic layers
- Arbitrary incident wave polarization (circular, linear, elliptical)
- Arbitrary incident wave angle of incidence
- Exactly solves Maxwell’s Equations for arbitrary layer stacks of any thickness
- Compute reflected power, transmitted power, and S-parameters
- Easy to use class-based syntax
- Large, fast-to-run test suite
