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.

Illuminating Quantum Phenomena in 2D Materials: The Power of Optical Spectroscopy

open access: yesAdvanced Optical Materials, EarlyView.
Atomically thin 2D materials host quantum tunnelling, plasmonic and excitonic phenomena driven by reduced dimensionality and strong many‐body interactions. This review links these effects to state‐of‐the‐art optical probes—NSOM, pump–probe, CARS, TRR, and optical frequency comb spectroscopy—highlighting how their ultrahigh spatial–temporal resolution ...

Graded Plasmonic Metagratings for Directional Nonlinear Optical Sensing

open access: yesAdvanced Optical Materials, EarlyView.
A refractometric sensing approach is presented, based on the angular variation of the emission pattern while changing the local environment. This method is first demonstrated on rectangular arrays, then on an aperiodic metagrating configuration designed to shape the first diffraction orders into a broadened band. Abstract Plasmon‐enhanced sensing based

Single‐Chamber Deposited Multilayered Parylene Films with Enhanced Visibility and Substrate Adhesion for Protective Device Coating

open access: yesAdvanced Optical Materials, EarlyView.
The multilayered parylene‐C films simultaneously achieve enhanced visibility and improved OLED performance. Visibility is controlled by tuning the dimer‐to‐monomer ratio during deposition, which modulates surface roughness, thickness, and void density.
