Are you interested in electro-optic modulators? Curious how a single device can guide both optical and microwave/THz waves with bandwidths up to 3 THz?
HYLAB’s Ph.D. student Yazan Lampert just published a Python notebook in the Tidy3D FDTD by Flexcompute Community Library where he walks through exactly that:

In this example, he shows how to compute the guided modes for both optical and terahertz frequencies, and how the structures in his example enable velocity matching for efficient THz–optical conversion.
