Pushing the Limits of Electron and Photon Interactions With Matter [Guest Editorial]

The articles in this special section focus on man-made nanostructures. Includes the following topics: the significance of advanced simulation tools as we face scaling challenges in electronics; 3D integrated photonics; and reducing the footprint and energy consumption of future 3D integrated microsystems through the use of thin-film lithium niobate technology in hybrid waveguide silicon photonics designs.
