On‐Chip Control of Electron Emission with an Active Terahertz Metasurface

open access: yesAdvanced Optical Materials, EarlyView.
A THz pulse drives Fowler‐Nordheim electron emission from gold dipole antennas. Changing the on‐chip DC bias bends the electron path toward or away from the bias pads. Abstract Terahertz (THz) radiation has emerged as a powerful tool for inducing ultrafast electron emission and controlling electron beams, with applications in photonics and electron ...

Polarization‐Controlled Strong Light–Matter Interaction With Templated Molecular Aggregates

open access: yesAdvanced Optical Materials, EarlyView.
Graphene nanoribbons act as a template for brick‐shaped organic semiconductor molecules. The templating results in optoelectronic properties resembling those of a single crystal. The templated layer supports optical transitions with well‐oriented transition dipole moments.

Development of High‐Performance Multilayer Monochromators

open access: yesAdvanced Optical Materials, EarlyView.
Detailed insights into the optical and multilayer design of Double Multilayer Monochromators (DMM) are presented and fully characterized, including key optimization strategies and solutions to fabrication challenges. By integrating in‐house Ion Beam Figuring and a high uniformity multilayer coating process, the developed DMMs achieve high reflectivity,
