Gigahertz free-space electro-optic modulators based on Mie resonances
Abstract Electro-optic modulators from non-linear χ (2) materials are essential for sensing, metrology and telecommunications because they link the optical domain with the microwave domain. At present, most geometries are suited for fiber applications. In contrast, architectures that modulate directly free-space light at gigahertz (GHz) speeds have remained very challenging, …
