Lesson 6 – Reconstruction of Unknown Grating

In this lesson we check that the layer peeling algorithm can reconstruct an unknown grating with knowledge of only the reflection coefficient. In the first step, we select a typical grating with chirp and apodization and calculate its reflection coefficient. This spectrum is then exported to a text file. In the next step, OptiGrating is…
