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,

Directionally Asymmetric Holographic Imaging for Arbitrary Polarization States Using Janus Metasurfaces

open access: yesAdvanced Optical Materials, EarlyView.
We demonstrate single‐layer titanium dioxide Janus metasurface holograms that achieve directionally asymmetric imaging under forward and backward illumination. By integrating the Dammann grating principle with precise phase control, our design produces high‐fidelity holographic images for arbitrary polarization states at 532 nm, simplifying fabrication,

Strong and Weak Coupling Nanophysics with Free Electron Beams

open access: yesAdvanced Optical Materials, EarlyView.
This paper focuses on a short review of the study of the coupling between optical excitations at the nanometer scale, made possible by recent advances in free electron beam spectroscopies. In particular, plasmon–plasmon, plasmon–exciton, and plasmon–phonon couplings are reviewed. Abstract The work of Luis M.
